please help on both 1.) We learned in section 6.1 that the Empirical Rule (a.k.a 68-95-99.7 rule) is a good estimate of probability within a specific number of standard deviations from the mean for any normal distribution. We know that this rule only provides a good estimate and that it is not very precise. With use of the Normalcdf function in our calculator, we can find exact values. For example, when using the Empirical Rule 95% is expected to be...

Verify the empirical rule by using Table A, software, or a calculator to show that for a normal distribution, the probability (rounded to two decimal places) within a. 1 standard deviation of the mean equals 0.68. b. 2 standard deviations of the mean equals 0.95. c. 3 standard deviations of the mean is very close to 1.00.
