Suppose that from previous experience, you know that given investment is normally distributed, has a mean return of 12%, and there is an 82% chance that the investment’s return is less than (or equal to) 16%. What is the standard deviation of the investment’s return?

please explain how to find z.

Suppose that you know that the weight of standard poodles is Normally distributed with a standard deviation of 4 pounds. You take an SRS of 10 poodles and find their average weight to be 52 pounds. Perform a significance test with this data to see if the average weight of standard poodles is 49 pounds or if it is actually larger than that. Use a 3% significance level. Fill in the blanks with each requested value. Write all numbers as...
