Question 1:A study is conducted to determine the effect that 3 different dogfood brands have on the mean lifetime of dogs. The study isconducted with 15 dogs (All of the same breed and gender) whoare made to eat one of the 3 brands of dog food their entire lives.Each of the dog food types is randomly assigned 5 dogs in thestudy.The Study began in 1991 and ended in 2001. (When the final dogDied). The dataset (Dog Food) shows the data of the Lifetimes ofthe dogs (In Months).1.1. Use the dataset (Dog_Food) to test the hypothesis that thepopulation mean lifetimes of dogs that eat the 3 different typesof dog food are the same and construct the Anova table basedon the dataset.1.2. Using the results of the ANOVA table, conclude whether themean lifetimes for the different brands differ. State all steps ofthe hypothesis. ul MINSA15:29O 8%Dog_Food.xlsxТуреLifetime110018817611151455643242962593106311331303125363

The data gathered from a survey of a random group of people about their smoking habits and their bodily weights are: a11 =159, a12 =203, a13 =10, a21 =285, a22 =500, a23 =38, a31 214, a32 -300, a33 =28, a41 =113, a42 =189, a43 =30, a51 =467, a52 1,969, a53 71 The following contingency table was created based on the above data, where you will need to calculate the grand total, the total for each row, and the total for each column on your own before answering the question that appears after the table.

An investigator analyzed the leading digits from 794 checks issued by seven suspect companies. The frequencies were found to be 218, 130, 106, 83, 65, 48, 48, 37, and 59, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud. Use a 0.025 significance level to test for goodness-of-fit with Benford's law. Does it appear that the checks are the result of fraud?
