3. Ten individuals are chosen at random from a normal population and their heights are found to be 63,63,66,67,68,69,70,70,71,71 inches. Test if the sample belongs to the population whose mean heights is 66 inches? Test at 95% confidence interval.

Answer #1

since test statistic does not falls in rejection region we fail to reject null hypothesis
we do not have have sufficient evidence to conclude that sample belongs to a population whose population mean is different from 66.

In the US, the population mean height for 3-yr-old boys is 38 inches. Suppose a random sample of 15 non-US 3-yr-old boys showed a sample mean of 37.2 inches with a standard deviation of 3 inches. Assume that the heights are normally distributed in the population. After conducting the hypothesis testing to determine whether the population mean for non-US boys is significantly different from the US population mean, we fail to reject the null hypothesis at 0.05 level. If you...
