An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study thespread of the virus, measure " distance" by the number of home ranges separating a group of gorillas from the first group infected. Hereare data on distance and number of days until deaths began in each later group:Use a calculator or software to find the following values.(a) Find the mean and standard deviation of .MEAN:STANDARD DEVIATION:(b) Find the mean and standard deviation of y.MEAN:STANDARD DEVIATION:(c) Find the correlation between and yrDistanceDays yE445 347418 304148 48

We need to obtain the means, standard deviations, and correlation coefficient between Distance, x,…

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 40 feet. Assume the population standard deviation is 4.9 feet. The mean braking distance for Make B is 44 feet. Assume the population standard deviation is 4.6 feet. At a = 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles?

Assume that the distribution of lengths of pop songs is nearly normal.Define your variable: Let p be the proportion of pop song that are seconds long. Let μμ be the mean length of the sampled pop songs, in seconds. Let μμ be the mean length of pop songs, in seconds.. Let p be the proprotion of songs in the sample. Create and interpret a 95% Confidence Interval. Round your answers to one decimal place. and seconds.What is the margin of error? Round your answer to one decimal place. seconds.According to Google, the mean length of pop songs is 210210. What do you think of this claim? The claim is inside the interval. It is reasonable. The claim is above the sample mean, so there is no way it can be true. The claim is inside the interval. It must be true. That claim is not in our…
