Welcome back Wabuda — missed you this week. a) Step 1: List all the collected data points and count the total number of observations. The data points are: 50, 80, 70, 58, 53, 50 49, 36, 76, 57, 64, 50 84, 71, 83, 72, 78, 75 84, 72, 69, 49, 66, 48 42, 65, 88 The total number of observations is n = 30. Step 2: Calculate the sum of all data points. x = 50+80+70+58+53+50+49+36+76+57+64+50+84+71+83+72+78+75+84+72+69+49+66+48+42+65+88 x = 1739 Step 3: Calculate the average (mean) number of minutes. The average is given by the formula x = ( x)/(n). x = (1739)/(30) ≈ 57.9667 Step 4: Suggest a suitable number of minutes based on the average. Based on the average of approximately 57.97 minutes, a suitable number of minutes to be added to the menu would be the closest whole number. The suitable number of minutes is 58 minutes. b) Step 1: Count the number of people who prefer minutes greater than 60 from the collected data. The values greater than 60 are: 80, 70, 76, 64, 84, 71, 83, 72, 78, 75, 84, 72, 69, 66, 65, 88. There are 16 such values. Step 2: State the estimated number of people. The estimated number of people who prefer minutes greater than 60 is 16. Send me the next one 📸
