Provide the requested table entry. The data in the following table reflect the amount of time 40 students in a section of Statistics 101 spend on homework each day. Determine the value that should be entered in the relative frequency column for the class 45-59. Homework time (minutes) | Number of students | Relative frequency 0-14 | 2 | 15-29 | 4 | 30-44 | 10 | 45-59 | 16 | 60-74 | 6 | 75-89 | 2 | 16 40% 0.4 16%

1) The data in the following table reflect the amount of time 40 students in a Statistics class spend on assignment each day. Time (minutes) Relative frequency 0 - under 15 0.05 15 - under 30 0.10 30- under 45 0.25 45- under 60 60- under 75 0.15 75- under 90 0.05 Determine the value of the missing relative frequency. Do not convert to percent. Keep to two decimal places.
Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set. The distribution of the numbers of hours that a random sample of college students study per week is shown in the pie chart. Use 32 as the midpoint for "30+ hours."
