The mean length of a group of fish is 14.2 inches. a fish that is 41 inches long joins the group. how does this fish’s length affect the mean

The new fish's length will increase the mean length of the group of fish.

Step-by-step explanation:

We have been given that the mean length of a group of fish is 14.2 inches. A fish that is 41 inches long joins the group.

Since the mean is sum of data values divided by the number of data points, so after adding a data point greater than mean, the mean will be increased.

As mean length of the group is 14.2 inches and the length of the new fish is 41 inches, which is greater than mean, therefore, the new fish's length will increase the mean length.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
