A program to decrease littering was carried out in four cities in California's Central Valley starting in August 2011. The amount of litter in the streets (average pounds of litter collected per block per day) was measured during July before the program started and then the next July, after the program had been in effect for a year. The results were as follows:

Question 15 of 16

Assure that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability that a given score Is between - 2.07 and 3.66 and draw a sketch of the region.

Sketch the region, Choose the correct graph below

The probability is ____.

(Round to four decimal places as needed.)

The overhead reach distances of adult females are normally distributed with a mean of 205.5 cm and a standard deviation of 8.3 cm.

a. Find the probability that an individual distance is greater than 214.80 cm.

b. Find the probability that the mean for 20 randomly selected distances is greater than 203.70 cm.

c. Why can the normal distribution be used in part b, even though the sample size does not exceed 30?

a. The probability is ____.

(Round to four decimal places s needed.)

b. The probability is ____.

(Round to four decimal places as needed.)

c. Choose the correct answer below.

◯ A. The normal distribution can be used because the original population has a normal distribution.

◯ B. The normal distribution can be used because the finite population correction factor is small.

◯ C. The normal distribution can be used because the mean is large

◯ D. The normal distribution can be used because the probability is less than 0.5

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all adults. (Accommodating 100% of adults would require very wide seats that would be much too expensive.) Assume adults have hip widths that are normally distributed with a men of 142 In. and a standard deviation of 0.9 in. Find P99. That Is, find the hip with for adults that separates the smallest 99% from the largest 1%

What is the maximum hip width that is required to satisfy the requirement of fitting 99% of adults?

____ in. (Round one decimal place as needed)

Assume that females have pulse rates that are normally distributed with a mean of = 72.0 beats per minute and a standard deviation of = 12.5 beats per minute.

Complete parts (a) through (c) below.

a. If 1 adult female Is randomly selected, find the probability that her pulse rate is less than 78 beats per minute.

The probability is ____.

(Round to four decimal places as needed.)

b. If 16 adult females are randomly selected. find the probability that they have pulse rates with a mean less than 78 beats per minute.

The probability is ____.

(Round to four decimal places as needed.)

c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?

◯ A. Since the mean pulse rate exceeds 30, the distribution of sample means is a normal distribution for any sample size.

◯ B. Since the original population has a normal distribution, , the distribution of sample means is a normal distribution for any sample size.

◯ C. Since the distribution is of sample means, not individuals, the distribution is a normal distribution for any sample size.

◯ D. Since the distribution is of individuals, not sample means, the distribution is a normal distribution for any sample size.

Find the areas of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.

The area of the shaded region is _____.

(Round to four decimal places as needed.)

Question 14 of 16

Assume that a randomly selected subject is given a bons density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability that a given score is less than - 0.78 and draw a sketch of the region.

Sketch the region. Choose the correct graph below

The probability is ____.

(Round to four decimal places as needed.)
