Decide whether or not to reject the null hypothesis in favor of the alternative hypothesis at significance level α = 0.05 α=0.05 based on the following information: n = 32 n=32, HA : μ ≠ 200 H A :μ =200, T = 0.001 T=0.001. I recommend that you sketch the area that represents the p-value.

1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....
