Suppose you know that the mean score (μ) on a measure of the personality trait “openness to experience” is 35.66 in a population of artists, with a standard deviation (σ) of 13.32. Next assume you went to Greenwich Village and gave this personality measure to a group of 10 artists. The mean in this sample was 40.33. You are interested in testing whether the 10 Greenwich Village artists were sampled from the same population described above. Calculate the standard error of the mean for this example.

To estimate the mean height μ of male students on your campus, you will measure an SRS of students. Heights of people of the same sex and similar ages are close to Normal. You know from government data that the standard deviation of the heights of young men is about 2.8 inches. Suppose that (unknown to you) the mean height of all male students is 70 inches. (a) If you choose one student at random, what is the probability that...

Suppose the height of individuals in a population follow a normal distribution with a mean (μ) of 66 inches and a standard deviation (σ) of 4 inches. a) Using the statistical software R, sample n individuals from the distribution described above. For N=10,000 iterations, compute the average height for n=5, n=15, n=50, n=100 individuals and plot a histogram of the sampling distribution of the Z score (?̅−??/√? ) b) Using the statistical software R, sample n individuals from the distribution...

Suppose you are interested in finding out how happy the students are at UNR. You design a survey that probes aspects of an individual’s emotional life, and using this survey are able to compute an accuracy index score ranging from 0 (completely miserable) to 100 (nauseatingly happy). You know that the standard deviation of the population (sigma) equals 8; however you do not know, and want to know, what the mean of the population (mu) is. Rather than give the...

You wish to test the claim that the average IQ score is less than 100 at the .005 significance level. You determine the hypotheses are: Ho: μ=100 H1:μ<100 You take a simple random sample of 76 individuals and find the mean IQ score is 95.5, with a standard deviation of 15.1. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known and once with assuming that it is known. Round to three decimal...
