Question

Can someone explain how to count the number of values that are between 7.26 and 11.64 that is on this example sheet. The answer is 12, but I can not find a solution to get me that answer.

Maria Bueno UO Homework a. Computex, s and s for this sample. The mean of a set of quantitative data is the sum of the measurements divided by the number of measurements contained in the data set. Use the formula below to find the value of the mean where xi is an individual measurement the of measurements Substitute and solve to find the mean. 7 11+ 9 7+ 8+ 5+ 9+ 20 9.45 The sample variance for a sample of n measurements is equal to the sum of the squared deviations from the mean divided by n-1. Use the formula given below to find the sample variance, s Substitute and solve to find s (7-9.45) (8-9.45) (9-9.45) 19 4.79 The sample standard deviation, s, is the positive square root of the sample variance, s s 4.79 -2.19 b. Count number of measurements in the intervals xts, xt2s, xt3s. Express each count as a percentage of the to num the of measurements Start by determining the values for xts using the mean of 9.45 and standard deviation 2 X s 7.26 X +S 11.64 Now count the number of values that are between 7.26 and 11.64. 12 Divide the number of values by 20 and multiply by 100 to find the percent. 2.53 JStaviantlPlt

Explanation / Answer

from above given 20 values are 10,9, 5,10,11,11,11,13,12,12,8,8,8,10,13,12,13,6,9,11

out of whcih values b/w 7.26 and 11.64 are 10,9,10,11,11,11,8,8,8,10,9,11 which are 12 in quanity.

please revert if need further clarification.
