Twelve percent of the world's population is left-handed. A researcher dlaims that left-handed individuals are more creative than those who aren't left-handed. Inorder to support his claim, he takes a sample of 1650 artists and finds that 10% of them are left-handed.Answer the following. (If necessary, consult a list of formulas.)(a) Find the mean of p, wherep is the proportion of left-handed individuals in a random sample of 1650.(b) Find the standard deviation of p.(c) Compute an approximation for P(p <0.1), which is the probability that there will be 10% or fewer left-handed peoplein a random sample of 1650. Round your answer to four decimal places.

Solution: From the given information, the out of 1650 artists 10% are left-handed. The population proportion is p =12%.a. The mean of p-hat isb.c.

Answered: Twelve percent of the world's…

Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, μ, spent by customers at the supermarkets has been reported to be 38 minutes, but executives have good reason to believe that u is different from 38 minutes. The executives hire a statistical consultant and ask her to perform a statistical test. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 44 minutes and the standard deviation of the times to be 10 minutes. Based on this information, complete the parts below. (a) what are the null hypothesis Ho and the alternative hypothesis H₁ that should be used for the test? Ho H₁ :0 (b) Suppose that the consultant decides not to reject the null hypothesis.

The price to earnings ratio (P/E) Is an Important tool in financial work. A random sample of 14 large U.S. banks (JP Morgan Chase, Bank of America, and others) gave the following P/E ratios.t 24 16 22 14 12 13 17 22 15 19 23 13 11 18 The sample mean is x = 17.1. Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of a certain stock index is H = 18. Let x be a random variable representing the P/E ratio of all large U.S. bank stocks. We assume that x has a normal distribution and o = 4.7. Do these data indicate that the P/E ratio of all U.S. bank stocks is less than 18? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses.
