Although the question's print is not clear, to the best of my knowledge, as I can see, We are given that:
and
No, we know that, by definition:
Thus, for the functions r and s which are defined for all real numbers x, the answer to the question asked is:
Answer:
0.6844 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $1,250
Standard Deviation, σ = $125
We are given that the distribution of daily sales is a bell like shaped distribution that is a normal distribution.
Formula:
We have to find
P(sales less than $1,310)
Calculation the value from standard normal z table, we have,
0.6844 is the probability that sales on a given day at this store are less than $1,310.
