1. A study claimed that there was a height difference between African elephants and Asian elephants. You take a random sample of 35 male African elephants, who averaged 9.3 feet at the shoulder. The population standard deviation of African elephants is 0.7 feet. Then you take a random sample of 41 male Asian elephants, who averaged 8.9 feet at the shoulder. The population standard deviation of Asian elephants is 0.6 feet. At the 1% significance level, use a hypothesis test to test the study’s claim.

A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief exective office (CEO) was at least 10 years. A survey of 120 companies reported in The Wall Street Journal found a sample mean tenure of 9.3 years for CEOs with a standard deviation of s = 5.3 years (The Wall Street Journal, January 2, 2007). You don't know the population standard deviation but can assume it is normally distributed....

Suppose you want to test the notion that individuals perceive a greater height difference between men and women than actually exists, due to stereotyping. The true population difference between the height of men and women is an average of 5 inches. You obtain a random sample of 400 individuals and record their perceptions of the mean difference in height between men and women. You find that the sample perceives the difference between men and women to average 6 inches. The...

Young and Company claims that its pressurized diving bell will, on average, maintain its integrity to depths of 2500 feet or more. You take a random sample of 50 of the bells. The average maximum depth for bells in your sample is 2455 feet. Set up an appropriate hypothesis test using Young and Company’s claim as the null hypothesis. Assume the population standard deviation is 200 feet. Use a 5% significance level. What is the p-value that you calculate for...

According to NCSA, (Next College Student Athlete) the mean vertical jumping height for outside hitters on Division 1 (D1) college female volleyball teams is 19.9 inches. A sports science researcher at a D1 school believes this is too low. From a simple random sample of 50 D1 outside hitters the reseacher calculated a mean vertical jumping height of 20.8 inches. Assuming the population standard deviation is 0.7 inches, answer the following questions. (a) State the null and alternative hypotheses as...

A.)You wish to test the following claim (HaHa) at a significance level of α=0.001α=0.001.  dd denotes the mean of the difference between pre-test and post-test scores.        Ho:μd=0Ho:μd=0 Ha:μd≠0Ha:μd≠0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: post-test pre-test 58 73.9 71.3 53.3 65.2 74.5 57.2 48.4 66.1 39.6 49.6 35.9 60.8 103.6 70.8 96.9 49.2 13.2 65.5 72.2 51.2 42.4 45.9 66.4 55.3 32...

In the United States, the populations mean height for 4-year-old boys is 39 inches. A researcher believes that non-U.S. 4-year-old boys are shorter than U.S. 4- year-old boys. Suppose a random sample of 32 non-U.S. 4-year-old boys showed a sample mean of 38.2 inches with a standard deviation of 3.1 inches. The boys were independently sampled. Assume that heights are Normally distributed in the population. Determine whether the population mean for non-U.S. boys is significantly shorter than the U.S. population...

Belmont and Marolla conducted a study on the relationship between birth order, family size, and intelligence. The subjects consisted of all Dutch men who reached the age of 19 between 1963 and 1966. These men were required by law to take the Dutch army induction tests, including Raven’s intelligence test. The results showed that for each family size, measured intelligence decreased with birth order: first-borns did better than second-borns, second-borns did better than third-borns, and so on. And for any...
