For this hypothesis test, information about the sample and a standard error from a randomization distribution are provided. H0: the mean = 26 Ha: the mean not = 26 n = 75, x bar = 25.5, s = 5.4 and the Standard Error estimated to be 0.6 (So .6 is an estimate for the standard deviation in the x bar distribution) Find the value of the standardized z-test statistic.

Hypotheses, the sample statistic, and the standard error are given. Find the value of the standardized z-test statistic and then use the standard normal distribution to find the p-value. Assume the sample size is large enough to use the standard normal distribution. Test H0 : p=0.35 vs Ha : p>0.35 when the sample has p^=0.41 and the standard error is SE=0.02. round to 3.dp test statistic= p-value=

This question is based on Ch10, but we can solve it using our knowledge from Ch9. In Ch 8, we created confidence intervals to test whether the means differed in a statistically significant manner between two independent (unrelated) populations, like males and females. The sample point estimator in the confidence interval was the difference in the sample means between the 2 samples (xbar - ybar). We created a confidence interval of the form: (xbar-ybar) +/- (Zα/2)[standard error of (xbar-ybar)] We...
