A true-false quiz with 10questions was given to a statistics class. Following is the probability distribution for the score of a
SSSSS [86.1K]

Using the mean <u>formula and it's interpretation</u>, it is found that:

1. The mean is 7.52.

2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.

The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.

Hence, in this problem, according to the <u>distribution given</u>, the mean is:

E(X) = 5(0.06) + 6(0.12) + 7(0.33) + 8(0.29) + 9(0.13) + 10(0.07) = 7.52

The mean is 7.52.

The <em>interpretation </em>is that over many trials, the mean would approach 7.52.

In a sample of 32 city residence, 24 reported that they take vitamin C supplement daily. There are 46,480 residence in the city.
Andreyy89

Answer:

34,860

Step-by-step explanation:

In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75

0.75 in  percentage is 75%. This means 75% of the residents in sample take Vitamin C.

We can expect the same percentage of people in entire population to take Vitamin C.

Total population of city = 46480

Expected number of residents who take vitamin C in the city = 75% of 46480

= 0.75 x 46480

= 34860

This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.
