Answer:
0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 8 minutes
Standard Deviation, σ = 2.5 minutes
Sample size, n = 25
We are given that the distribution of time spent is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(sample mean is between 7.8 and 8.2 minutes)
0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
The monthly earning of two employees are determined by the number of products they sell in that month, plus a fixed amount.
Employee X:
Each month, this employee earns $245 per product sold plus $1,600.
Employee Y:
E = 270p + 1,750, where E is the monthly earnings and p is the number of products sold.
(How much does each employee earn if they do not sell any products that month?
Employee X earns $[?]
Employee Y earns $[?]
Answer:
