Neatly write up your work for the following problem ON ITS OWN SHEET OF BLANK PAPER: You measure 40 dogs' weights, and find they have a mean weight of 43 ounces. Assume the population standard deviation is 12 ounces. Based on this, construct a 99% confidence interval for the true population mean dog weight. Do not use StatCrunch. Show all formulas used, work, etc. Be sure to define your variables. As in the reading, in your calculations: --Use z = 1.645 for a 90% confidence interval --Use z = 1.96 for a 95% confidence interval --Use z = 2.576 for a 99% confidence interval Give your answer as an inequality rounded to one decimal place.

Neatly write up your work for the following problem ON ITS OWN SHEET OF BLANK PAPER:
You measure 40 dogs' weights, and find they have a mean weight of 43 ounces. Assume the population
standard deviation is 12 ounces. Based on this, construct a 99% confidence interval for the true
population mean dog weight.
Do not use StatCrunch. Show all formulas used, work, etc. Be sure to define your variables., As in the
reading, in your calculations:
--Use z = 1.645 for a 90% confidence interval
--Use z = 1.96 for a 95% confidence interval
--Use z 2.576 for a 99% confidence interval
