For a two-sided z-test, the test statistic is equal to 1.62. What is the p-value for this test equal to?

32. When we state the alternative hypothesis to look for a difference in a parameter in any direction, we are doing a A) one-sided test B) two-sided test C) None of the above.

Suppose we wish to test the hypotheses Ho:u= 10 versus H.: u<10, where u represents the mean age of non-high school aged children who are members of a large gymnastics club in a metropolitan area. Assume age follows a Normal distribution with o=2. A random sample of 16 ages is drawn from the population, and we find the sample mean of these observations to be X = 8.76. 34. What is the value of the test statistic? A) Z=-0.62 B) z=-1.24 C z =-2.48 D) Z=-9.92

In performing a chi-square goodness of fit test for a normal distribution, if there are 7 intervals, then the degrees of freedom for the chi-square statistic is ______________.
