Find the probability that a piece of data picked at random from a normally distributed population will have a standard score that is a. less than 3.00. b. greater than -1.55. c. less than -0.75. d. less than 1.24. e. greater than -1.24.

Step 1
00, we need to find the area under the normal curve to the left of 3.00. This can be done using a standard normal distribution table or a calculator. The probability is the area to the left of 3.00, which is approximately 0.9987. b. Show more…

NORMAL CURVE OF z-score if a random variable has the standard Normal distribution, what are the possibilities that it will take on a value? a. less than 1.54, b. greater than - 0.40 c. greater than 0.76 d. less than - 1.35 e. between 0.90 and 1.40 f. between - 0.45 and - 0.66 ?

Find the probabilities that a random variable having the standard normal distribution will take on a value (a) less than 1.72; (b) less than -0.88; (c) between 1.30 and 1.75; (d) between -0.25 and 0.45.

Given that $z$ is a standard normal random variable, compute the following probabilities. $$\begin{array}{l} (a) {P(-1.98 \leq z \leq .49)} \\ (b) {P(.52 \leq z \leq 1.22)} \\ (c) {P(-1.75 \leq z \leq-1.04)}\end{array}$$
