Suppose a random sample of 100 observations from a binomial population gives a value of p = 0.45 and you wish to test the null hypothesis that the population parameter p is equal to 0.40 against the alternative hypothesis that p is greater than 0.40. Complete parts a through c. a. Noting that p = 0.45, what does your intuition tell you? Does the value of p appear to contradict the null hypothesis? O A. Yes, because p satisfies Hg:p>0.40...

Use the following information to complete steps (a) through (d) below. A random sample of size n = 31 results in a sample mean of 123.3 and a sample standard deviation of 8.5. An independent sample of size n2 = 50 results in a sample mean of 129.8 and sample standard deviation of 7.3. Does this constitute sufficient evidence to conclude that the population means differ at the x = 0.005 level of significance? (a) What type of test should...
