Please use R-Studio to answer the following question.

I mentioned that dnorm(x, mean, sd) doesn’t give the probability of being exactly equal to x. So what does it give? It gives you the height of the normal curve at that x. Plot the graph of a normal random variable with mean 50 and standard deviation 10. Note you will have to create range of xvalues between 0 to 100. Then find the probability using dnorm() then use plot() command

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...

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 following questions 1. An eductional theorist collects behavioural data from two groups of children in an early childhood center. She measures how much time the children are active (e.g. running or swinging on the monkey bars) in minutes. The first group of children are encouraged to run about and as such are expected to be active; the second group is encouraged to sit still and paint, and are expected to be less active....

Use R studio to answer the following. A study was carried out to investigate the variation of rainbow trout weights in a certain creek. The weights (in kilograms) of 10 randomly selected fish are listed below: 0.78, 0.45, 0.35, 0.76, 0.57, 0.42, 0.33, 0.68, 0.66, 0.42 Assume that the population is approximately normally distributed. Hint: make a vector to enter the weight data into R, e.g.: > wt = c(0.78, ..., 0.42) Find the 90% confidence interval for the unknown population...
