Step-by-step explanation:
Answer: a. 374.4321
Step-by-step explanation:
Taking the central limit theorem(number of samples is large) into consideration, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/(σ/√n)
Where
x = annual sales per square foot .
µ = mean annual sales per square foot
σ = standard deviation
n = number of samples
From the information given,
µ = $370
σ = $38.54
n = 64
The probability value is 18/100 = 0.18
Looking at the normal distribution table, the z score corresponding to the probability value is - 0.92
Therefore,
- 0.92 = (x - 370)/(38.54/√64)
x - 370 = - 0.9 × 4.8175 = 4.33575
x = 370 + 4.4321 = $374.4321
Answer:

Step-by-step explanation:
Be VERY careful. When it write out the equation that way, it will give the speculation of this:

Now, in this case, since you were extra explanatory about this [what is written in parentheses], two factors I know of that multiply to 15 are these:
