Jeffrey, аs аn eight-yeаr оld, established a mean time оf 16.43 secоnds for swimming the 25-yard freestyle, with a standard deviation of 0.8 seconds. His dad, Frank, thought that Jeffrey could swim the 25-yard freestyle faster using goggles. Frank bought Jeffrey a new pair of expensive goggles and timed Jeffrey for 15 25-yard freestyle swims. For the 15 swims, Jeffrey's mean time was 16 seconds. Frank thought that the goggles helped Jeffrey to swim faster than the 16.43 seconds. Conduct a hypothesis test using a preset α = 0.05. Assume that the swim times for the 25-yard freestyle are normal A. Draw the normal curve to indicate what kind of test (one or two tailed) B. Null and Alternative Hypothesis C. Calculator or Desmos function used D. Test Statistic and P-Value E. Final conclusion that addresses the original claim.
