The median number of part-time employees at fast-food restaurants in a particular city was known to be 18 last year. City officials think the use of part-time employees may be increasing. A sample of nine fast-food restaurants showed that seven restaurants were employing more than 18 part-time employees, one restaurant was employing exactly 18 part-time employees, and one restaurant was employing fewer than 18 part-time employees. Can it be concluded that the median number of part-time employees has increased

Answers

Answer:

It can be concluded that the median number of part-time employees has increased hence we will reject the null hypothesis ( H0 : p = 0.5 )

Step-by-step explanation:

Test using  α = 0.5 to determine whether the median number of part-time employees has increased

number of restaurants with more than 18 part-time employees = 7  ( + sign )

number of restaurants with less than 18 part-time employees = 1 ( - sign )

number of restaurants with exactly 18 part-time employees = 1

first step : ( state the null and alternate hypothesis )

Null hypothesis : ( H0) : median ≤ 18

Alternate hypothesis : ( Ha ) : median ≥ 18

The size of the sample ( n ) can be considered to be 8 because

number of restaurants with more than 18 part-time employees = 7  ( + sign )

number of restaurants with less than 18 part-time employees = 1 ( - sign )

Hence the actual hypothesis that should be tested will be :

H0 : p = 0.5

Ha : p ≠ 0.5

Next apply the binomial distribution to determine the number of + signs

= nP = 8 ( 0.5 ) = 4 + signs ( right tailed test i.e. upper tail of the binomial distribution )

determine the P ( ≥ 7 ) + signs in order to obtain the p-value of this right tailed test ( using the binomial probability table )

P ( ≥ 7 )+ signs  = p(7) +signs  + p(8)+signs

                         = 0.0313 + 0.0039 = 0.0352

Hence the P-value = 0.0352  is < 0.05  hence we will reject the Null hypothesis ( H0 : p = 0.5 )

hence It can be concluded that the median number of part-time employees has increased

The true statement is that, the median number of part-time employees has increased

The given parameters are:

[tex]\mathbf{n_1 = +7}[/tex] ---- restaurants with more than 18 part-time employees[tex]\mathbf{n_2 = -1}[/tex] ---- restaurants with less than 18 part-time employees [tex]\mathbf{n_3 = 1}[/tex] ---- restaurants with exactly 18 part-time employees

Using a 0.5 test of significance, the null and the alternate hypotheses are:

Null hypothesis : [tex]\mathbf{H_0 : p= 0.5}[/tex]Alternate hypothesis : [tex]\mathbf{H_a : p \ne 0.5}[/tex]

The sample size (n) is calculated using

[tex]\mathbf{n =n_1 -n_3}[/tex]

So, we have:

[tex]\mathbf{n =7 --1}[/tex]

[tex]\mathbf{n =8}[/tex]

The mean of the distribution is:

[tex]\mathbf{\bar x = np}[/tex]

This gives

[tex]\mathbf{\bar x = 8 \times 0.5}[/tex]

[tex]\mathbf{\bar x = 4}[/tex]

Using the right tailed test, we calculate the probability that a restaurant has more than 7 part-time employees.

This is calculated as:

[tex]\mathbf{P(x \ge 7+) = P(x = 7+) + P(x = 8+)}[/tex]

Using the binomial probability table, we have:

[tex]\mathbf{P(x \ge 7+) = 0.0313 + 0.0039 }[/tex]

[tex]\mathbf{P(x \ge 7+) = 0.0352}[/tex]

By comparison,

When the p-value is less than the level of significance, then we will reject the Null hypothesis

Hence, it can be concluded that the median number of part-time employees has increased

Answers

Part (a)

Answer:   x = -8

------------------

Work Shown:

2(x-1) = 3(x+2)

2x-2 = 3x+6 .... distribute

2x = 3x+6+2 .... adding 2 to both sides

2x = 3x+8

2x-3x = 8 .... subtracting 3x from both sides

-x = 8

x = -8 ..... multiply both sides by -1

===========================================================

Part (b)

Answer:  x = 5/11

------------------

Work Shown:

-4(2x-2) = 3(x+1)

-8x+8 = 3x+3 ..... distribute

-8x = 3x+3-8 .... subtract 8 from both sides

-8x = 3x-5

-8x-3x = -5 ... subtract 3x from both sides

-11x = -5

x = -5/(-11) .... divide both sides by -11

x = 5/11

In decimal form, this is approximately equal to 5/11 = 0.4545

Kanye and his two friends are sharing the cost of lunch. the total cost of the bill is $15.27 . if Kanye has $20, how much will he have left after he pays his share?​

Answers

Answer:$4.73

Step-by-step explanation:

Answer:

If Kayne is with his two friends, that means there are three people in total.

If there are three people sharing the price of this lunch, each person would have to pay 15.27/3 dollars.

Dividing, we get that each person must pay 5.09 dollars.

Subtracting 5.09 from 20, we have that Kayne will have $14.91 left after paying his share.

Answer:

y = 1.5x

Step-by-step explanation:

We are to find the equation of the line

The equation is expressed as y = MX+c

m is the slope

c is the intercept

Get the slope

Using the coordnate (10, 15) and (20, 30)

m = 30-15/20-10

m = 15/10

m = 1.5

Get the intercept

Substitute m = 1.5 and (10, 15) into y = mx+c

15 = 1.5(10) + c

15 = 15+c

c = 0

Get the equation

y = mx+c

y = 1.5x+0

y = 1.5x

Hence the required equation is y = 1.5x

The graph of an exponential function passes through (1, 10) and (4, 80). Find the function that describes the graph.

Answers

Answer:

y = 5*2ˣ

Step-by-step explanation:

Exponential function:

y = abˣ

Ordered pairs given:

(1, 10) and (4, 80)

Substitute x and y values to get below system:

10 = ab80 = ab⁴

Divide the second equation by the first one and solve for b:

80/10 = b³b³ = 8b = ∛8b = 2

Use the first equation and find the value of a:

10 = a*2a = 5

The function is:

y = 5*2ˣ

Answer:

[tex]y=5 \cdot 2^x[/tex]

Step-by-step explanation:

An exponential function is written in the form:

[tex]y=ab^x[/tex]

We can use the given points that the exponential function passes through to solve for a and b.

Create a system of equations by substituting (1, 10) and (4, 80) into the exponential form of a function.

[tex]\text{I}:\ 10=ab^1[/tex] [tex]\text{II}: \ 8 0=ab^4[/tex]

Divide Equation I by Equation II in order to cancel out variable a.

[tex]\displaystyle \frac{80=ab^4}{10=ab}[/tex][tex]8=b^3[/tex][tex]b=2[/tex]

Now we can solve for a by substituting b back into either equation from the system of equations.

[tex]10=ab[/tex] [tex]10=a(2)[/tex] [tex]a=5[/tex]

Substitute 5 for a and 2 for b into the form of an exponential function to find the exponential function that passes through (1, 10) and (4, 80).

[tex]y=5 \cdot 2^x[/tex]

y = 5 · 2ˣ is the exponential function that describes the graph.

n+n+23 = 107

2n = 107-23

2n = 84
