Need part C

An article in Fortune magazine reported on the rapid rise of fees and expenses charged by mutual funds. Assuming that stock fund expenses and municipal bond fund expenses are each approximately normally distributed, suppose a random sample of 12 stock funds gives a mean annual expense of 174 percent with a standard deviation of 0.38 percent, and an independent random sample of 12 municipal bond funds gives a mean annual expense of 0.75 percent with a standard deviation of 0 39 percent. Let Hy be the mean annual expense for stock funds, and let it be the mean annual expense for municipal bond funds. Do parts a, b, and c by using the equal variances procedure a (c) Calculate a 95 percent confidence interval for the difference between the mean annual expenses for stock funds and municipal bond funds. Can we be 95 percent confident that the mean annual expense for stock funds exceeds that for municipal bond funds by more than 5 percent? (Round your answers to 3 decimal places.) Yes the intervalisatiove 0.6 The interval
