Aresearcher 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

421,5 calories in average

Explanation:

There are 5 participants, but 1 participant  came out of the study, in this order of ideas only it is neccesary to add the estimate values of calories per person (450+426+310+500), the result is 1.686, that result need to be devided by the four participants to find the average of calories that they consume, 1686 divided by 4 is equal 421,5 calories in average
