One of the events at field day was the long jump. The lengths of 20 jumps are shown. If the mean is 7.0 cm and the standard deviation is 0.8 cm, does the data appear to be normally distributed? Explain. 7.2 5.4 7.5 7.2 7.7 7.5 6.7 5.5 8.0 6.9 6.7 6.0 7.9 8.0 * 6.3 7.7 7.4 5.5 6.4 7.7 525

Fuel efficiency of Prius:  Fueleconomy.gov, the official US government source for fuel economy information, allows users to share gas mileage information on their vehicles. The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not guaranteed. (a) The EPA claims that a 2012 Prius gets 50 MPG (city and highway mileage combined). Do these data provide strong evidence against this estimate for drivers who participate on fueleconomy.gov? The test statistic is: __________________(please round to two decimal places)The p-value:___________________________ for this hypothesis test is:  (please round to four decimal places)(c) Please comment on the primary thing that is wrong about the following statement: There is sufficient evidence…
