Consider the following sample: 8 26 27 34 36 45 48 51 52 53 54 60 62 64 76 80 85 92
the mean and sample standard deviation of which are 52.9444 and 22.0013.
What is the z-score of '52'? (Leave your answer to 2 decimals: ex: 1.23)

The size of a certain cell is 2.5*10^-9m. another cell is 1.5*10^3 times larger. how large is the larger cell in scientific notation?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Solve the formula ax+ by = c for x.
