Determine the two values of z such that the middle 61% of the data lie between the two z-values. Round the solutions to two decimal places, as z- values are traditionally rounded. The middle 61% of the data lie between z = and z =

Can you help me answer iv, v, and vi using R please? my answers for i,ii, and iii can be seen below. Thank you!   1. Researchers found that the speed of a prey (twips/s) and the length of prey (twips x 100) are good predictors of the time (s) required to catch a prey. (A twip is a measure of distance used by programmers). Data were collected in an experiment in which subjects were asked to "catch" an animal prey moving across his or her computer screen by clicking on it with the mouse. The investigators varied the length of the prey and the speed with which prey moved across the screen. ```{r}prey <- read.csv("https://www.siue.edu/~jpailde/prey.csv")prey```   i) Fit a multiple regression model for predicting catch time using prey length and speed as predictors.    ii) Construct 95\% confidence interval for the regression slopes of each predictor. Interpret your result. Will the interpretation change if you change the confidence level to 90\% and 99\%?    iii) Predict the catch time…
