A sample of heights of 64 English men has a mean of 170 cm. and a standard deviation of of 6.4 cm, while a sample of heights of 60 Americans has a mean of 172 cm. and a standard deviation of 6.3 cm. Test the claim that Americans are on average taller than the English men at a level of significance of 0.05? The null hypothesis is The alternative hypothesis is The test statistic is The tabulated value(s) is(are) The decision is The conclusion is

Step 1
- Null Hypothesis (H0): The mean height of American men is equal to or less than the mean height of English men. Mathematically, H0: μ_American ≤ μ_English. - Alternative Hypothesis (H1): The mean height of American men is greater than the mean height of English Show more…

The average height of men in the United States is 5 feet, 9 inches (69 inches). The mean height among a sample of 54 NBA players is 6 feet 5 inches (77 inches) with a standard deviation of 5 inches. You are to examine whether NBA player height differs from the U.S. average for men. State the null and alternative hypotheses for a one-tailed hypothesis. b. Test the null hypothesis retaining a Type I error of 5% (α = 0.05), and please show your work.

A sociologist wishes to test the hypothesis that executives at large companies are taller than the average population. The population distribution is assumed to be normal, and the standard deviation for male American executives is 3.1 inches. Suppose that a random sample of 15 male American executives has a mean of 70.5 inches. Test the hypothesis that the mean height of male American executives is above the average height of 69 inches for American men. (a) State the null hypothesis and alternative hypothesis. (b) Calculate the z-test statistic. (c) Calculate the P-value. (d) Is the result significant at the level α = 0.05? Why? (e) What would change if a two-sided alternative had been used?

State the null hypothesis, $H_{o},$ and the alternative hypothesis, $H_{a},$ that would be used for a hypothesis test for each of the following statements: a. The mean age of the youths who hang out at the mall is less than 16 years. b. The mean height of professional basketball players is greater than $6 \mathrm{ft} 6$ in. c. The mean elevation drop for ski trails at eastern ski centers is at least 285 feet. d. The mean diameter of the rivets is no more than 0.375 inch. e. The mean cholesterol level of male college students is different from $200 \mathrm{mg} / \mathrm{dL}$
