E Question Help A concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The following data represent the strength of nine randomly selected casts Compute the mean, median and mode strength of the co rete (in psi) Compute the mean strength of the concrete Select the correct choice below and, if necessary fill in the answer box to complete your choice psi) 3970. 4090. 3300, 3000, 2930, 3840, 4090, 4040. 3590 A. The mean strength of the concrete is [] psi of pressure B. The mean does not exist Compute the median strength of the concrete Select the correct choice below and, if necessary fill In the answer box to complete your choice Round to the nearest tenth as needed) A The median strength of the concrete is psi of pressure. Round to the nearest tenth as needed) The median does not exist Compute the mode strength of the concrete Select the correct choice below and, it necessary, fil in the answer box to complete your choice The mode of the strengths of the concrete is psi of pressure Round to the nearest tenth as needed) O A.

Explanation / Answer

Sol:

Rcode is :casts <- c(3970,4090,3300,3000,2930,3840,4090,4040,3590)
sort(casts)
mean(casts)
median(casts)
mode(casts)

the mean strength of the concrete is 3650

median strength of concrete is 3840

mode of the concrete is 4090
