What does the line "Test of mu = 2.63 vs mu not = 2.63" mean?
Mu stands for mean of the observed values. The line means that a statistical test is being run to determine whether the mean is actually 2.63. Correct?

Explain why Binom(613, 0.5) is well approximated by Norm(306.5, 12.38).

Why would we use rows 281 and 332 to find the bounds for the 95% confidence interval? What interval do you obtain?

Help would be greatly appreciated ASAP, as assignment is due in 2 hours!
