Here is the completed table:
Has pet Has no pet Total
7th grade 102 48 150
8th grade 107 68 175
Total 209 116 325
<h3>What is a two-way table?</h3>
A two way table is used to show the frequency of two categorical variables. Information are usually presented in rows and columns.
- The 7th grade students that have no pets = 150 - 102 = 48
- The 8th grade students that have pets = 175 - 68 = 107
- Total students that have pets = 102 + 107 = 209
- Total students that have no pets = 48 + 68 = 116
- Total = 209 + 116 = 325

Answer:
P(x = 0) = 0.004
P(x = 0) = 0.047
P(x = 0) = 0.211
P(x = 0) = 0.422
P(x = 0) = 0.316
Step-by-step explanation:
We are given the following information:
We treat a person who does not become a repeat offender as a success.
P(Success) = P(person who does not become a repeat offender) = 0.75
Then the number of people follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 4
We have to evaluate:

yfhjn
Step-by-step explanation:
Answer: C
Step-by-step explanation: I chose this answer because in 8th graders, their mean is 6 and their range is 9, that’s a difference of 3. But in 4th graders, their mean is 5 and their range is 6, so there isn’t much of a difference for 4th graders. The answer couldn’t be A, B, or D so I came to the conclusion that it’s C. (Sorry if this explanation doesn’t make sense but I hope I got the right answer.)
