Question 1. In January 2005, a company that monitors Internet traffic (WebSideStory) reported that its sampling revealed that the Mozilla Firefox browser launched in 2004 had grabbed a 4.6% share of the market. I. If the sample were based on 2,000 users, could Microsoft conclude that Mozilla has a less than 5% share of the market? II. WebSideStory claims that its sample includes all the daily Internet users. If that’s the case, then can Microsoft conclude that Mozilla has a less than 5% share of the market?

the data in the accompanying table represent the rate of return
Question Get Answer the data in the accompanying table represent the rate of return of a certain company stock for 11 months, compared with the rate if return if a certain index of 500 stocks. bith are in percent. complete parts a through d below. the estimate of B0 is: the estimate of B1 is: assuming the residuals are normally distributed, test whether a linear relation exists between the rate of return of the ibdex,x, and the tate of return for the company stock,y, at the a=.010 level of significance. choose the correct answer below. state the null hypothesis. determine the p value for this hypothesis test. state the appropriate conclusion qt the x=0.10 level of significance. assuming the residuals are normally distributed, construct a 90% confidence interval ror the slope of the true least squares regression line. lower bound is: upper bound is: what is the meab rate of return for the company stock if the rate of return of the index is 3.25%?

The population standard deviation is not assumed to be known, so you have to rely on the sample standard deviation. Compute with Excel a 95 per cent confidence interval estimate of the population mean.How would your result change for a 99 per cent confidence interval? Explain in words the economic intuition of your conclusion.

Many older homes have electrical systems that use fuses rather than
Question Many older homes have electrical systems that use fuses rather than circuit breakers. A manufacturer of 30-amp fuses wants to make sure that the mean amperage at which its fuses burn out is in fact 30. If the mean amperage is lower than 30, customers will complain because the fuses require replacement too often. If the mean amperage is higher than 30, the manufacturer might be liable for damage to an electrical system as a result of fuse malfunction. To verify the mean amperage of the fuses, a sample of fuses is selected and tested. If a hypothesis test is performed using the resulting data, what null and alternative hypotheses would be of interest to the manufacturer?a.H0: μ = 30 versus Ha: μ
