Answer: The maximal margin of error is 4.822.
Step-by-step explanation:
Since we have given that
Number of bags = 38
Sample mean = 78 ounces
Standard deviation = 14.5 ounces
At 96% confidence interval for the true population mean bags of nut weight.
So, z = 2.05
As we know that formula for "Margin of error":
Hence, the maximal margin of error is 4.822.

Answer:
a. 405
b. -2
c. 5
d. 43
Step-by-step explanation:
I don't like doing arithmetic any more than you do, so I let a calculator do it for me. A spreadsheet works well for this, too. The function values are shown in the attachment.
Put the function argument where the variable is and do the arithmetic.
a. h(4) = 5·3^4 = 405
b. d(2) = 7 -9(2 -1) = -2
c. h(0) = 5·3^0 = 5
d. d(-3) = 7 -9(-3 -1) = 43
