The sample data below shows the number of hours spent by five students over the weekend to prepare for Monday's Business Statistics exam. 3 12 2 3 5(See the Excel Data File.) The 75 th percentile of the data is the closest to .g

(i) 90%

(ii) 10%

Step-by-step explanation:

Given the data as;

Weather condition            on-time        Delayed        Total

Sunny                                   167                 3                 170

Cloudy                                  115                  5                 120

Rainy                                      40                 15                 55

Snow                                        8                 12                  20

Total                                      330              35                 365

The marginal distribution of arrival status in percentages =arrival status total/total sum *100

(i) on-time = 330/365 * 100 = 90.42 = 90%

(ii) Delayed = 35/365 *100 =9.58 = 10%
