Thanks will rate! 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 A's operating expenses were $28.00 per...

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.** ```{r} class1<-c(100,...

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 cloud 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....

Please Use R studio to answer the question. This is the Statistics section of Comparing Groups. 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) Test an appropriate hypothesis as...
