(d) What is the probability that a random sample of 16 people will exceed the weight limit?An elevator at a college has a posted weight limit of 2,700 pounds, and a maximum capacity of 16 people. We determined that if thesample mean x 2 168.75 for a particular sample of 16 people, then the weight capacity will be exceeded. We are asked to determinethe probability that a random sample of 16 people will exceed the weight limit.We previously determined the mean and standard deviation of the sampling distribution of x.H- - 165- - 8.25We are given that the distribution of weights of individuals on campus is approximately normal, so the sampling distribution of x isapproximately normal also. We can calculate the desired probability by standardizing. Recall the standardization formula.b- -PK z b) = z2.In other words, we need to find the following. (Round your answer to four decimal places.)- 1652 168.75) = Pz28.25= 1-

Mean is 165 and a standard deviation is 8.25.

According to a study conducted by a statistical organization, the proportion of people who are satisfied with the way things are going in their lives is 0.78. Suppose that a random sample of 100 people is obtained. Complete parts (a) through (e) below. different people feel differently regarding their satisfaction. D. The sample proportion p is a random variable because the value of p represents a random person included in the sample. The variability is due to the fact that people may not be responding to the question truthfully. (c) Describe the sampling distribution of p, the proportion of people who are satisfied with the way things are going in their life. Be sure to verify the model requirements. Since the sample size is no more than 5% of the population size and np(1 - p) = 17.16 2 10, the distribution of p is approximately normal with Ha = 0.780 and On = 0.041 .

A researcher believes that 52.5% of people who grew up as the only child have an IQ score over 100. However, unknown to the researcher, this figure is actually 50%, which is the same as in the general population.To attempt to find evidence for the claim, the researcher is going to take a random sample of 400 people who grew up as the only child. Let p be the proportion of people in the sample with an IQ score above 100. Answer the following: a) Find the mean of p: b)Find the standard deviation of p: c) Compute an approximation for P(p ≥ 0.525), which is the probability that there will be 52.5% or more people with IQ scores over 100 in the sample. Round your answer to four decimal places.
