A random sample of 663 teens who said they did not typically eat fast food reported an average daily calorie intake of 2258, with standard deviation 1519. A random sample of 413 teens who said they did typically eat fast food reported an average daily calorie intake of 2637, with standard deviation 1138. The two populations are moderately positively skewed. Based on the above description, which of the following conditions are met for conducting a hypothesis test for the equality of two means?
a. Both samples are random
b. Samples are independent of one another
c. Both samples are normal enough given the sample size
d. Two population means need to be the same
Answer:
Option B
Step-by-step explanation:
The sample populations are independent of each other and hence for comparing of mean of two population it is very essential that the two populations independent of each other.
Now here one population set consist of only people who eat fast food and the other set of population consists of people who do not eat fast food.

In the email data set in Chapter 1, the number variable de- scribed whether no number (labeled none), only one or more small numbers (small), or whether at least one big number appeared in an email (big). Of the 3,921 emails, 549 had no numbers, 2,827 had only one or more small numbers, and 545 had at least one big number. (a) Are the outcomes none, small, and big disjoint
Answer:
These outcomes are disjoint.
Step-by-step explanation:
(a) Are the outcomes none, small, and big disjoint
If they are disjoint, the sum of the total number of each has to be equals to the number of emails.
We have:
3921 emails.
549 with no numbers.
2827 with only one or more small numbers
545 had at least one big number.
549 + 2827 + 545 = 3921
Since the sum is equals to the number of emails, these outcomes are disjoint.

15 3/4percent is equal to which decimal
Answer:
Step 1: Multiply the whole number by the denominator:
15 3/4 = 15.75
Step-by-step explanation:
Step 1: Multiply the whole number by the denominator:
15 × 4 = 60
Step 2: Add the product you got in Step 1 to the numerator:
60 + 3 = 63
Step 3: Divide the sum from Step 2 by the denominator:
63 ÷ 4 = 15.75

If 5 hours is 25% of the time a trip will take, how long will it take?
Answer:
20 hours
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
We know that 25% is 1/4 of the time. So 5 hours would be multiplied by 4, which is the reciprocal of 1/4.
5 x 4 = 20, so that's your answer. I hope I helped :)

A hot dog bun (volume 240cm3) with a density of 0.15g/cm3 is crushed in a picnic cooler into a volume of 195cm3. What is the density of the bun?
Answer:
weight of hot dog bun = 240 cm^3 x 0.15 g/cm^3 = 36 gram
36 gm / 195 cm^3 = 0.185 g/cm^3
Step-by-step explanation:
Density is mass/volume. The mass of the bun never changes, only its volume. Solve for the original mass.
Now think about it logically. Should the bun be more sense now that it has been crushed? Of course! The math proves it.
Therefore the answer is: 0.185 g/cm^3

A submarine travels at an elevation of -75 3/4 ft relative to sea level. Then its elevation changes by -16 3/8 ft. What is the new elevation of the submarine? Show your work
Answer:
The new navigation height of the submarine is -62.25 feet.
Step-by-step explanation:
Given that a submarine travels at an elevation of -75 3/4 ft relative to sea level, and then its elevation changes by -16 3/8 ft, to determine what is the new elevation of the submarine the following calculation must be performed:
3/4 ft = 0.75 ft
-75 x 0.75 = -56.25 ft
3/8 ft = 0.375 ft
-16 x 0.375 = -6 ft
-56.25 + -6 = -62.25
Thus, the new navigation height of the submarine is -62.25 feet.

Write the explicit formula for the sequence. 27,18,12,8
Answer:
a(n) = 27*(2/3)^(n - 1)
Step-by-step explanation:
The first four terms are 27, 18, 12, 8.
Find the common ratio:
To do this, let that ratio = r, and write and solve 27r = 18. Thus, r = 2/3.
The general explicit formula for this sequence is
a(n) = a(1)*(2/3)^(n - 1), or, since a(1) = 27, a(n) = 27*(2/3)^(n - 1)

Lilly, Madelyn, Natalie, and Olivia each walked from their houses to the mall. Lilly walked 1/4 mile, Madelyn walked 3/8 mile, Natalie walked 5/6 mile, and Olivia walked 7/12 mile. what is the order of these distanced from least to greatest?
Answer:
1/4, 3/8, 7/12, 5/6
Step-by-step explanation:
First, change all the fractions so they have the same denominators. The least common denominator is 24. 1/4=6/24 3/8=9/24 5/6=20/24 7/12=14/24
Now, put them in order from least to greatest: 6/24, 9/24, 14/24, 20/24
