A bond analyst is analyzing the interest rates for equivalent municipal bonds issued b wo different states. At a = 0.05, is there enough evidence to conclude that there is a difference in the interest rates paid by the two states? State A State B Sample size Mean interest rate (%) 60 60 3.2 3.4 Population variance A) Yes, because the test value -5.86 is outside the critical region -1.96

1. Conduct a two-sample t-test at a 1% level of significance to find out if the U.S. stock returns significantly outperform the U.S. corporate bond returns using the monthly data covering the sample period 1980-2019. Please explain the hypothesis and how to use the summary to answer the question.
A study was performed concerning risk factors for carotid-artery stenosis (arterial narrowing) among 264 men. The data reported is: Sample size Mean Standard deviationGroup 1: No stenosis 156 5.3 1.4Group 2: Stenosis 108 5.1 0.8 The test stastistic F is assumed to be 3.06 to check the equal variance. Question: Suppose researchers want to test if there is a significant difference in mean blood-glucose level between men with and without stenosis considering the critical F test is 1.35 with a equal variance (pooled), what is the test statistic for this test ?

9) Steel rods are manufactured with a mean length of 25 centimeters (cm). Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed, with a standard deviation of 0.07 cm. What proportion of rods has a length less than 24.9 cm? b. C. d. 25 Any rods that are shorter than 24.85 cm or longer than 25.15 cm are discarded. What proportion of rods will be discarded? Using the results of part (b), if 5,000 rods are manufactured in a day, how many should the plant manager expect to discard? If an order comes in for 10,000 steel rods, how many rods should the plant manager manufacture if the order states that all rods must be between 24.9 cm and 25.1 cm?
