Consider a sample of 52 football games where 32 of them were won by the home team use a 0.01 significance level to test the claim that the probability that the home team wins is greater than one half

Answers

According to the information given, it is found that:

The hypothesis tested are:

C. [tex]H_0: p = 0.5[/tex], [tex]H_1: p > 0.5[/tex]

The test statistic is z = 1.66.The p-value of the test is of 0.0485.The conclusion is:

Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.

At the null hypothesis, it is tested if home teams win half their games, that is, if the proportion is of 0.5, hence:

[tex]H_0: p = 0.5[/tex]

At the alternative hypothesis, it is tested if home teams win more than half their games, that is, if the proportion is of more than 0.5, hence:

[tex]H_1: p > 0.5[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.

For this problem, the parameters are:

[tex]p = 0.5, n = 52, \overline{p} = \frac{32}{52} = 0.6154[/tex]

Hence, the value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.6154 - 0.5}{\sqrt{\frac{0.5(0.5)}{52}}}[/tex]

[tex]z = 1.66[/tex]

The test statistic is z = 1.66.

The p-value is the probability of finding a sample proportion above 0.6154, which is 1 subtracted by the p-value of z = 1.66.

Looking at the z-table, z = 1.66 has a p-value of 0.9515.

1 - 0.9515 = 0.0485.

The p-value of the test is of 0.0485.

Since the p-value is greater than 0.01, the conclusion is:

Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.

Using technology, the least square regression line equation which models the data is : y = -0.3x + 35.

b.) The slope of −0.3 means that the birth rate is decreasing by about 3 births per 1000 people every 10 years. The y-intercept of 35 means that in 1960 there were 35 births per thousand people.

Given the data :

X : __ 0 ___ 10 ____ 20 ___ 30 ___ 40 ___ 50Y:__35.4 __33.6 ___28.3 __27.0 __22.4 _ 20.0

Using either a linear regression calculator or excel :

y = -0.3x + 35 Slope, b = - 0.3 Intercept, c = 35

The value of the slope, gives the rate of change in y per unit increase in x.

Hence, the slope value of - 0.3 means that birth rate is decreasing by about 30 births per 1000 people.

The intercept is the value of y when x = 0 ; This means that the number of births in 1960(beginning of the data collection), there were 35 births per thousand people.

jamie baked 48 cookies, which is 8 less than twice the number of cookies gina baked what is the equation

Answers

So we know that the number x is multiplied by 2 and subtracted by 8 to get the total number of cookies that Gina baked. Lets set up this equation.  

48 = 2x - 8

The 2x is our x multiplied by 2 and the - 8 is the 8 less.  

Lets solve:  

48 = 2x - 8  

Add 8 to both sides to isolate the x variable:

48 + 8 = 2x - 8 + 8

56 = 2x    

Now we divide the 2 from the 2x in order to fully isolate the variable:  

56 = 2x  

28 = x

Lets plug 28 in to double check the answer:  

48 = 2(28) - 8  

48 = 56 - 8

48 = 48  

Yes!

After the transformation of 270° clockwise rotation we get K(7, 4)→K'(-4, 7). Therefore, option B is the correct answer.

The given coordinate point is (7, 4).

What is the transformation?

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

Rotation of object 270° clockwise direction

The rule of rotating a figure 270 degrees clockwise is (x, y)→(-y, x)

So, K(7, 4) rotated by 270° clockwise we get K'(-4, 7).

After the transformation of 270° clockwise rotation we get K(7, 4)→K'(-4, 7). Therefore, option B is the correct answer.

Hong's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Hong  $5.80  per pound, and type B coffee costs  $4.20  per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of  $700.60 . How many pounds of type A coffee were used?​

Answers

Answer:

31 Pounds

Step-by-step explanation:

Let x = the number of lbs of Type A coffee.

 

We know that this month's blend used 4 times as many pounds of type B coffee as type A coffee.

Total lbs of coffee =  x + 4x

 

The total cost then is:

($ cost for Type A)(x) + ($ cost for Type B)(3x) = $700.60

 

$5.80x + $4.20(4x) = $700.60

$5.80x + $16.8x = $700.60

$22.6x = $700.60

x = 31 lbs

Therefore they where 31 pounds of type A coffee used.

Answer:

Step-by-step explanation:

-6k-10=10-10k

-6k-10=-10k+10

-6k-10=-10k+10

-6k-10+10=-10k+10+10

-6k=-10k+20

-6k=-10k+20

-6k+10k=-10k+20+10k

4k=20 4k/4 = 20/4

k=20/4

k=5

Answer: K = 5

Step-by-step explanation:

Rearrange your terms

-6k - 10 = 10 - 10k - Before

-6k - 10 = -10k + 10 - after rearrange

Then add 10 to both sides

-6k - 10 = -10k + 10 - before adding 10

-6k - 10 + 10 = -10k + 10 + 10 - After adding 10

Simplify- add the numbers

-6k - 10 + 10 = -10k + 10 + 10  

-6k = -10k + 10 + 10

-6k = -10k + 10 + 10

-6k = -10k + 20

-6k = -10k + 20

Add 10k to both sides again

-6k = -10k + 20

-6k + 10k = -10k + 20 + 10

Simplify again- combine like terms

-6k + 10l = -10k + 20 + 10k

4k = -10k + 20 + 10k

4k = -10k + 10 + 10k

4k = 20

Divide both sides by K

4k = 20    = K = 5

4       4
