A researcher investigated some of the variables related to "fast starts," the acceleration and speed of a hockey player from a stopped position. Sixtysix hockey players, varsity and intramural, from a certain university were included in the experiment. Each player was required to move as rapidly as possible from a stopped position to cover a distance of 6 meters. The mean and standard deviation of the 66 individual average acceleration measurements over the 6-meter distance were 2.762 and 0.589 m/sz, respectively. (a) Find a 95% condence interval (in m/sz) for this population mean. (Round your answers to three decimal places.) 2 m/s2 to m/5 Interpret the interval. 0 In repeated sampling, 5% of all intervals constructed in this manner will enclose the population mean. 0 There is a 5% chance that an individual sample mean will fall within the interval. 0 There is a 95% chance that an individual sample mean will fall within the interval. 0 In repeated sampling, 95% of all intervals constructed in this manner will enclose the population mean. 0 95% of all values will fall within the interval. (b) Suppose you were dissatised with the width of this condence interval and wanted to cut the interval in half by increasing the sample size. How many skaters (total) would have to be included in the study? (Round your answer up to the nearest whole number.) n = skaters
