A person can take either of two routes to work, through Matteson or Richton Park. Both take on average 35 minutes, and travel times are Normally distributed. But are the variances of the travel times different? A random sample with n = 8 from Matteson route and n = 6 from Richton Park route showed a variance of 40 (units: square minutes) and 30 respectively. To test whether the variances are different, the following test of hypothesis should be done:

H0: sigma subscript 1 superscript 2 space equals space sigma subscript 2 superscript 2

H1:  sigma subscript 1 superscript 2 space not equal to space sigma subscript 2 superscript 2

To test at 5% level of significance, what is the critical value for the test statistic? (Give two decimal places)

    1.) 2.) A person can take either of two routes to work, through Matteson or Richton Park. Both take on average 35 minutes, and travel times are Normally distributed. But are the variances of the travel times different?

    Two processes for manufacturing large roller bearings are under study. In both cases, the diameters (in centimeters) are being examined. A random sample of 26 roller bearings from the old manufacturing process showed the sample variance of diameters to be s2 = 0.231. Another random sample of 28 roller bearings from the new manufacturing process showed the sample variance of their diameters to be s2 = 0.146. Use a 5% level of significance to test the claim that there is...

    Please answer neatly and correctly! Amy has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Amy has recorded the travel times for samples of eight trips via the 10 Freeway and eight trips via the 60 Freeway. The following table gives the travel...

    There are three routes I can take to get from school to home. Every day when I leave, I randomly select which route I will take (i.e. I am equally likely to take each of the three routes). Route 1 takes 3 minutes, Route 2 takes 5 minutes, and Route 3 takes 7 minutes. (a) What is the expected time it will take me to get home? (b) What is the variance of the time it will take me to...

    Dorothy Stanyard has three major routes to take to work. She can take Tennessee Street the entire way, she can take several back streets to work, or she can use the expressway. The traffic patterns are, however, very complex. Under good conditions, Tennessee Street is the fastest route. When Tennessee is congested, one of the other routes is preferable. Over the past two months, Dorothy has tried each of route several times under different traffic conditions. This information is summarized...

    To test H0: mean = 80 vs. H1: mean < 80, a simple random sample of size n = 22 is obtained from a population that is known to be normally distributed. (a) If x-hat = 76.9 and s = 8.5 compute the test statistic (b) If the researcher decides to test the hypothesis at the a = 0.02 level of significance, determine the critical value. (c) Draw a t-distribution that depicts the critical region (d) Will the researcher reject...

    Ashley Miller has three major routes to commute to work: take RiverView Street the entire way, take several back streets, or use the expressway. The traffic patterns are pretty complex. Under good conditions, RiverView Street is the fastest route; however, when it is congested, one of the other routes is usually preferable. Over the past two months, Ashley has tried each route several times under different traffic conditions. Her travel time to work (in minutes) is summarized in the following...
