Question 5,8.10 i will answer pliz help

Google doc link 1. What is the probability that a single randomly chosen value (from 1 to 100) would be over 65? [Note that this is a uniform distribution, so don't use the NormalCdf command, think of it like a spinner with 100 slots] 2. What is the probability that the mean of a group of 5 randomly chosen values (from 1 to 100) would be over 65? The NormalCdf command is now appropriate. [Note the population mean is 50.5 for all the questions on this activity. The SD is 29.01, but when you group of 5 means together, it shrinks the SD down. In this case, these would then have an SD 0f 29.01/sqrt(5) = 12.97] 3. Look over the google doc what proportion of size 5 samples have a mean over 65?7 How close did we get to the proportion the mathematics in #2 predicts? 4. What is the probability that the mean of a group of 20 randomly chosen values (from 1 to 100) would be over 65? [ Again, when you group means together, it shrinks the SD down. In this case, these would then have an SD 0f 29.01/sqrt(20) = 6.49] 5. Look over the google doc what proportion of size 20 samples have a mean over 65?7 How close did we get to the proportion the mathematics in #4 predicts? 6. What is the probability that a single randomly chosen value (from 1 to 100) would be between 40 and 60? [Note that this is a uniform distribution, so don't use the NormalCdf command, think of it like a spinner with 100 slots] 7. What is the probability that the mean of a group of 5 randomly chosen values (from 1 to 100) would be between 40 and 607 [see #2 for the SD] 8. Look over the google doc what proportion of your group's samples of 5 have a mean between 40 and 60? How close did we get to the proportion the mathematics in #7 predicts? 9. What is the probability that the mean of a group of 20 randomly chosen values (from 1 to 100) would be between 40 and 607 [see #4 for the SD] 10. Look over the google doc what proportion of your group's samples of 20 have a mean between 40 and 60? How close did we get to the proportion the mathematics in #9 predicts
