Short Answer

Expert verified

The first assumption for one-way ANOVA is that the each population from which sample is taken is assumed to be normal.

Step by step solution

01

Step-1 Given Information

Given in the question that there are five basic assumptions that must be fulfilled in order to perform a one-way ANOVA test. we have to write one assumption. .

02

Step-2 Explanation

A one-way ANOVA is a type of statistical testaims to assess multiple mutually exclusive theories about our data.it is used to determine the significance difference among several group means. The first assumption for one-way ANOVA is that the each population from which sample is taken is assumed to be normal.

61. degrees of freedom - numerator: df(num)=

Three students, Linda, Tuan, and Javier, are given five laboratory rats each for a nutritional experiment. Each rat’s weight is recorded in grams. Linda feeds her rats Formula A, Tuan feeds his rats Formula B, and Javier feeds his rats Formula C. At the end of a specified time period, each rat is weighed again and the net gain in grams is recorded.

Two students are interested in whether or not there is variation in their test scores for math class. There are 15 total math tests they have taken so far. The first student’s grades have a standard deviation of 38.1. The second student’s grades have a standard deviation of 22.5. The second student thinks his scores are more consistent.

What is the p-value?

Two coworkers commute from the same building. They are interested in whether or not there is any variation in the time it takes them to drive to work. They each record their times for 20commutes. The first worker’s times have a variance of 12.1. These coworkers' times have a variance of 16.9. The first worker thinks that he is more consistent with his commute times. Test the claim at the 10% level. Assume that commute times are normally distributed. What is s2 in this problem?

Suppose a group is interested in determining whether teenagers obtain their driver's licenses at approximately the same average age across the country. Suppose that the following data are randomly collected from five teenagers in each region of the country. The numbers represent the age at which teenagers obtained their driver's licenses.
