Answer:

The value of the mean will increase

Explanation:

A researcher asks participants to estimate the calories they consume in a meal. The researcher records the following estimates: 450, 426, 310, 500, and 220. If the researcher removes the estimate of 220 (perhaps because the participant drops out of the study), then the value of the mean will <u>increase</u>.

The working below shows that once 220 is removed from the consideration, the mean will increase;

With 220 in consideration:

(450+426+310+500+220)/5

mean = 381.2

Without 220 in consideration:

(450+426+310+500)/4

mean = 421.5
