Introduction to Empirical Economics

PART1:
Application
The Excel file HMWK2sample contains 100 observations, X, drawn from a distribution that is
n(μ,1). Use Excel and your own computations to calculate:
• P(24.9 ≤ μ ≤ 25.1) based only on observations 1 through 50; and
• P(24.9 ≤ μ ≤ 25.1) based on all 100 observations.
You can use Excel to compute the sample means based on the above three samples.
But i want you to write the descriptions of the results or anything regarding this excel after doing the calculation
in a document from after doing the work of the question on excel.
Part 2:
Given a random sample size of n = 1, 600 from a binomial
probability distribution with P = 0.40, do the
following:
a. Find the probability that the number of successes
is greater than 650.
b. Find the probability that the number of successes
is fewer than 530.
c. Find the probability that the number of successes
is between 550 and 650.
d. With probability 0.09, the number of successes is
fewer than how many?
e. With probability 0.20, the number
