so its 20 fixed or constant. so that +20
the 30 varies absed on teh number of days which is unknown . so that's 30x
do f(x)= 30x + 20
so for 4 days its
f(x) = 30(4) + 20
f(x) = 120+ 20 = 140
Answer:

Step-by-step explanation:
Given
See comment for data
Required
The lower limit 94% confidence interval
First, calculate the mean




Next, calculate the standard deviation using:

So, we have:




For 94% interval, the z score is

So, the margin of error (E) is:




The confidence interval of the true mean is:

The lower limit (L) is:



and the upper limit (U) is
