A study examined the average pay for men and women entering the workforce as doctors for 21 different positions.

(a) If each gender was equally paid, then we would expect about half of those positions to have men paid more than women and women would be paid more than men in the other half of positions. Write appropriate hypotheses to test this scenario.

(b) Men were, on average, paid more in 19 of those 21 positions. Complete a hypothesis test using your hypotheses from part (a).

(a)

If each gender was equally paid, then proportion of positions to have men paid more than women is equal to the proportion of positions to have women paid more than men. Let p shows the true proportion of positions to have men paid more than women.

Hypotheses are:

(b)

Conclusion: There is evidence to conclude that each gender was not equally paid.

5) The average height of women is ̄y = 64.5 inches, the average
height of men is ̄y = 67.5 inches. For both the standard deviation
is about s = 3 inches. (a) Suppose you take a sample of 4 women and
4 men. Construct a 95% CI for both. Do the confidence intervals
overlap? (b) Now repeat using a sample of 225 men and 225 women. Do
the confidence intervals overlap? (c) Can you explain what
happened? Why is...

A study was done on body temperatures of men and women. The
results are shown in the table. Assume that the two samples are
independent simple random samples selected from normally
distributed populations, and do not assume that the population
standard deviations are equal. Use a 0.05 significance level for
both parts.
