Use R studio

As of March 23, 2020, the number of COVID19 cases in the state of Florida was 1007, with 13 deaths. The number of cases in Louisiana was 837, with 20 deaths. We are interested in comparing the state’s mortality rates.
1. Construct a 95% confidence intervals for the difference of the two unknown population proportions. Draw some conclusions.
2. Test the hypothesis that the state of Louisiana has a higher mortality rate at a = 0.1.
  1. What are the null and alternative hypotheses?
  2. What is the test statistic, and p-value?
  3. What decision and conclusion should you make?
3. Would we get a different answer using a = 0.05?

On March 29th the number of confirmed cases of the Covid-19 per state was obtained from the internet. A random number generator was used to get the sample data on the sheet named Sample data What is the lower boundary on the 95% confidence interval for the whole number average of confirmed Covid 19 cases in the country? What is the upper boundary on the 95% confidence interval for the whole number average of confirmed Covid 19 cases in the...

THIS QUESTION REQUIRES THE USE OF R STUDIO. ANY ANSWERS GIVEN THAT ARE NOT IN R STUDIO CODE WILL NOT SUFFICE. SOLVING WITHOUT THE USE OF R STUDIO IS NOT ACCEPTABLE. The previous question was: Annual salaries for a large company are approximately normally distributed with a mean of 49000 dollars and a standard deviation of 2000 dollars. One manager claims that all of his direct reports are paid "above the 75th percentile" for the company. What is the minimum...

** Number 2 implemented in R (R Studio) ** Set up the Auto data: Load the ISLR package and the Auto data Determine the median value for mpg Use the median to create a new column in the data set named mpglevel, which is 1 if mpg>median and otherwise is 0. Make sure this variable is a factor. We will use mpglevel as the target (response) variable for the algorithms. Use the names() function to verify that your new column...

As of March 31, 2020, there are 113 confirmed cases of the current pandemic in Kane County, Illinois, and 6 confirmed deaths. 2a. Using these statistics, estimate the probability of a randomly-selected confirmed case of the virus in Kane County leading to death. Your probability in 2a does not really apply to all people, but to get an idea of what that number means, assume your answer to 2a applies to everyone who contracts the virus. 2b. If a family...

1. Use R Studio: Include R Code A survey is taken of 250 students, and a phat of 0.48 is found. The same survey is repeated with 1000 students, and the same phat value is found. Compare the two 95% confidence intervals. What is the relationship between them? Is the margin of error for the second one four times smaller? If not, how much smaller is it?

Using R Studio/R programming... Usually, we will use a random sample to estimate the statistics of the underlying population. If we assume a given population is a standard normal distribution and we want to estimate its mean, which is the better technique to estimate that mean from a sample: Use the mean of one random sample of size 500 Use the mean of 300 random samples of size 10 Run your own experiment and use your results as a supporting...
