Answer:
0.048 is the process yield of the group hired by Pandora.
Step-by-step explanation:
Number of employees hired by Pandora = 14
Each employee made the calls = 76
Total number of calls made by the employees = 14×76
= 1064
Out of 68 people number of people who subscribed = 51
Therefore, group's process yield =
=
= 0.04793
≈ 0.048
0.048 is the process yield of the group hired by Pandora.
Answer:
The standard deviation of the age distribution is 6.2899 years.
Step-by-step explanation:
The formula to compute the standard deviation is:
The data provided is:
X = {19, 19, 21, 25, 25, 28, 29, 30, 31, 32, 40}
Compute the mean of the data as follows:
Compute the standard deviation as follows:
Thus, the standard deviation of the age distribution is 6.2899 years.
