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. Then interpret your answer in a complete sentence within the context of the problem. Before you write up this question, watch the videos below.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
