Consider the following results for independent samples taken from two populations; Sample 1 N 400 X 0.48 Sample 2 N300 X 0.36 A. What is the 90% confidence interval for the difference between the two population proportions? Round your answers to four decimal places B. What is the 95% confidence interval for the difference interval between the two population proportions? Round you answer 2 decimal places and use a 0 in front of the decimal places.
We have provided a sample mean, sample size, and population standard deviation. In each case, use the one-mean z-test to perform the required hypothesis test at the 5% significance level. x = 20, n = 24, σ = 4, H0: μ = 22, Ha: μ ≠ 22
Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher wants to know if people find baby animals cuter than adult animals. All of the participants in a study are shown 10 pictures of baby animals and 10 pictures of adult animals. They are asked to rate (on a 1 to 10 scale) how cute they think each animal is.
Question Help Y 12.2.79 The number of successes and the sample size for a simple random sample from a population are given below. x = 8, n = 40, Ho:p=0.4, H2: p< 0.4, a = 0.01 a. Determine the sample proportion. b. Decide whether using the one-proportion z-test is appropriate. c. If appropriate, use the one-proportion z-test to perform the specified hypothesis test.

The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
