Samples of 400 men and 200 women sit an accountancy exam. The men have a mean mark of 51.2% while the women have a mean mark of 53.7%. The standard deviations are 11.14% and 10.0% respectively. Does this indicate that women on average have better marks? (Use 1% level of significance)

You are interested in wage gender differences. You have a random sample of the population. The sample mean hourly wage for men is KSH 22 while it is KSH 19 for women. The standard deviations of these samples are respectively, 6.1 and 7.1. How can you calculate the standard error of the difference in means? A. It is (6.1/number of men in the sample) + (7.1/number of women in the sample) B. It is the square root of (7.1 –...
