A sports analyst collects a data set to study the performances of hockey players in NHL. The data set has a variable named Time on Ice (TOI) which shows how long an NHL player stayed on ice in a game. Using this data set, the analyst calculates the sample mean for the TOI variable as 15 minutes and the standard deviation for the TOI variable as 3.4 minutes. Since the analyst plans to use the sample mean they calculate as a point estimate for the average TOI in NHL, they also calculate the margin of error for their point estimate as 0.5747. What must be the sample size of the data set in order to obtain the margin of error value as 0.5747? Submit your answer using the drop-down menu given below
