19. The data below are annual high values of Dow Jones
Industrial Average and annual mean sunspot numbers for eight recent
years. A sunspot number is a measure of sunspots or groups of
sunspots on the surface of the sun. The Dow Jones Industrial
Average is a commonly used index that is a weighted mean calculated
from different stock values.

1) This exercise uses the normal probability density function and
requires the use of either technology or a table of values of the
standard normal distribution.
The cash operating expenses of the regional phone companies during
the first half of 1994 were distributed about a mean of $29.77 per
access line per month, with a standard deviation of $2.65. Company

Please solve in R studio. Thanks in advance!
**Below are two samples of test scores from two different calculus
classes. It is believed that class 1 performed better than class
two. From previous tests it is known that the test scores for both
classes are normally distributed and the population standard
deviation of class 1 is 10 points and the population standard
deviation of class 2 is 8 points. Do the data support that class 1
performed better.**

Hello, i have this excersice in R studio
Write a function in R that generates simulations of a Poisson random variable as follows: define I = [λ], and use p_i + 1 = λp_i / (i + 1) to determine F recursively. Generate a random number U, determine if X≤I by comparing if U≤F (I). If X≤I searches downwards starting at I, otherwise it searches upwards starting from I + 1. Compare the time it takes for the two algorithms...

Can You please Answer the question using R studio and R

Telomeres are complexes of DNA and protein that cap chromosomal
ends. They consist of the same short DNA sequence TTAGGG repeated
over and over again. They tend to shorted with cell divisions and
with advancing cellular age, which will lead to chromosome
instability or apoptosis (programmed cell death).
Eukaryotic cells have the ability to reverse telomere shortening
by expressing telomerase, an
enzyme that extends the telomeres of chromosomes....

One month before the election, a poll of 630 randomly selected
votes showed 54% planning to vote for a certain candidate. A week
later, it became known that he had had an extramarital affair, and
a new poll showed only 51% of 1010 voters supporting him. Do these
results indicate a decrease in voter support fo his candidacy?

A machine used to fill gallon sized paint cans is regulated so
that the amount of paint dispensed has a mean of 128 ounces and a
standard deviation of 0.20 ounce. You randomly select 40 cans and
carefully measure the contents. The same mean of the cans is 127.9
ounces. Does the machine need to be reset? Explain your
reasoning.
