Anational car rental company recently conducted a study in which cars with automatic and standard transmissions (factor a – sample) were rented to male and female customers (factor b – columns). three customers in each category were randomly selected and the miles driven per day was recorded as follows: part a: clearly write all of the relevant hypotheses for this test design. part b: if you were to use an alpha level of 0.05 to test whether there is significant interaction between factors a and b. what should be the critical f value to define the rejection region for this test?

A national car rental company recently conducted a study recently in which cars with automatic and standard transmissions (factor B) were rented to male and female customers (factor A). Three customers in each category were randomly selected and the miles driven per day was recorded as follows:

Based on the design of this study, how many degrees of freedom will be associated with the mean square for factor A?

8312

70,000 + 6,000 + 800 + 30

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
