Question

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 ______.

Answer 1

421,5 calories in average

Step-by-step 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
