Answer:
By the Empirical Rule,
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
The symbol of a standard deviation is . So
When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus how many sigma?
By the Empirical Rule,
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.
