For reasonable distances, a certain jogger can maintain an average speed of 6 miles per hour while running on level ground. the jogger decides to go to a local park and use one of the paths there for a workout routine one day each week. this path is a gently sloping one that winds its way to the top of a hill. 1. the jogger can run at an average speed of 5.5 miles per hour up the slope and 6.5 miles per hour going down the slope. the jogger decides to cover 2 miles by going uphill for 1 mile and then returning 1 mile back down the hill. a. how long does it take the jogger to run 1 mile uphill? __ (hint: use the formula d = rt.) b. how long does it take the jogger to run 1 mile downhill? (hint: use the formula d = rt.) c. use your answers to a and b to determine how long, in hours, the full trip will take (1 mile uphill and 1 mile downhill). give an exact answer expressed as a fraction in simplest terms and then give a decimal approximation correct to three decimal places. reduced fraction: decimal approximation:

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
