You have found the following ages (in years) of all 6 lions at your local zoo: 13, 2, 1, 5, 2, 7 What is the average age of the lions at your zoo? What is the standard deviation? Round your answers to the nearest tenth.

What is the simplified expression for 6(2(y+x))

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.

Given a normal distribution with µ =50 and σ =4, what is the probability that 5% of the values are less than what x values? between what two x values (symmetrically distributed around the mean) are 95 % of the values? instructions: show all your work as to how you have reached your answer. don’t simply state the results. show graphs where necessary.
