Large samples of women and men are obtained, and the hemoglobin level is measured in each subject. here is the 95% confidence interval for the difference between the two population means where the measures from women correspond to population 1 and the measures from men correspond to population 2 -1.76 g /dl < u1 - u2< - -1.62 g /dl.

1. what does the confidence interval suggest about equality of the mean hemoglobin level in women and the mean hemoglobin level in men?

2. Write a brief statement that interprets the confidence level.

3. what is the confidence level? The formula?

For all hypothesis tests: Assume all samples are simple random samples selected from normally distributed populations. If testing means of two independent samples, assume variances are unequal. For each test give the null and alternative hypothesis, p-value, and conclusion as it relates to the claim. In a random sample of 360 women, 65% favored stricter gun control laws. In a random sample of 220 men, 60% favored stricter gun control laws. Test the claim that the proportion of women favoring...
