Step-by-step explanation:
First, let's start with what we have. If we use here's what we can put in:
Then we can use one of the given points to find the y-intercept. Since the only complete one is (12,10), we'll use that.
So now we have .
Now we can use our other point with the missing y-value and solve for y.
So the missing value is 64.

Answer:
the minimum sample size n = 11.03
Step-by-step explanation:
Given that:
approximate value of the population standard deviation = 49
level of significance ∝ = 0.01
population mean = 38
the minimum sample size n = ?
The minimum sample size required can be determined by calculating the margin of error which can be re[resented by the equation ;
Margin of error =
n ≅ 11.03
Thus; the minimum sample size n = 11.03
