At a 9% level of significance, what is the proper decision? Reject H0H0 Fail to reject H0Question 16 A null hypothesis H0 was rejected at the significance level = 0.10.

- Suppose that a random sample of size 1 is to be taken from a finite population of size N. a. How many possible samples are there?b. Identify the relationship between the possible sample means and the possible observations of the variable under consideration.c. What is the difference between taking a random sample of size 1 from a population and selecting a member at random from the population?The table below summarizes data from a survey of a sample of women. Using a 0.01significance level, and assuming that the sample sizes of 800 men and 300 women are predetermined, test the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. Does it appear that the gender of the interviewer affected the responses of women? Gender of Interviewer Man Woman Women who agree 498 247 Women who disagree 302 53 Compute the test statistic, rounding to three decimal places. Find the critical value(s).

- Calculate the statistic needed to test the hypothesis stated in Question 11 based on your sample of 1,000 throws of a goat astragalus.1. Using all 1991 birth records in the computerized national birth certificate registry compiled by the National Center for Health Statistics (NCHS), statisticians Traci Clemons and Marcello Pagano found that the birth weights of babies in the United States are not symmetric ("Are babies normal?" The American Statistician, Nov 1999, 53:4). However, they also found that when infants born outside of the "typical" 37-43 weeks and infants born to mothers with a history of diabetes are excluded, the birth weights of the remaining infants do follow a Normal model with mean μ = 3432 g and standard deviation σ = 482 g. The following questions refer to infants born from 37 to 43 weeks whose mothers did not have a history of diabetes.Compute the z-score of an infant who weighs 2002 g. (Round your answer to two decimal places.)?Approximately what fraction of infants would you expect to have birth weights between 2880 g and 4040 g? (Express your answer as a decimal, not a percent, and round to…As a result of dog breeding for certain physical traits, many dog breeds have changed in the last 100 years. A dog breeder wants to measure the effects of breeding on the face length of the boxer breed using a hypothesis test.
