Answer:

Relative frequency of male nonparticipation is O.42

Explanation:

Figure 1 is your partially filled frequency table.

1. Complete the table

(a) Total No

Total Yes + Total No = Total

102 + Total No = 187

Total No = 187 - 102

= 85

(b) Female No

Male No + Female No = Total No

40 + Female No = 85

Female No = 85 - 40

= 45

(c) Female Yes

Female Yes + Female No = Female Total

Female Yes + 45 = 95

Female Yes = 95 - 45

= 50

(d) Male Yes

Male Yes + Female Yes = Total Yes

Male Yes + 50 = 102

Male Yes = 102 - 50

= 52

(e) Male Total

Male Yes + Male No = Male Total

52 + 40 = Male Total

Male Total = 92

Figure 2 shows the completed table.

2. Frequency of Male No

There are 92 males, of whom 40 do not participate in an after-school activity.

The relative frequency of male nonparticipation is

40/92 = 0.43
