Professor Venkat is on a mission to find out the average number
of students absent from his lectures. For this, he analyzed 14
random attendance sheets from his previous semesters and found out
that on average, the number of absentees was 38 with a standard
deviation of 12. Let's assume that the data follows a Gaussian
distribution. Construct a 99% confidence interval for the true mean
of the dataset.

You are rolling a fair dice 100 times.
Let N be the number of times out of 100, when you roll an odd
number. What is the most suitable distribution for N? Type one of
the following (Poisson, binomial,
normal,geometric) .
Determine the probability that the number of times N out of
100, when you roll an odd number is 60 or more P ( N ≥ 60 )
= (use R and round to the third decimal place).
Which distribution is...

Recent data show that Americans consume, on average, more than
three times the recommended level of sodium per day in their food
and beverages. High salt intake contributes to high blood pressure
and its complications-stroke, heart attack, congestive heart
failure, and kidney failure. In fact, thousands of lives could be
saved if sodium consumption were lowered in people with high blood
pressure. Write a memo (i.e., a brief report) for the U.S.
