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...

Using only the 68-95-99.7 rule answer the following question. Let the variable Z be a z-score of a normal distribution. Calculate P(Z ≤ 3). Draw a picture of the situation first. Shade the area that corresponds to the desired proportion being sought. Please explain how you would use the 68-95-99.7 rule to solve this. If you can, how would you solve this using technology rather than the rule?
