Answer:
We conclude that the value of the mean is 40.
Step-by-step explanation:
We know that the researcher records the following estimates: 40, 46, 30, 50, and 34. If the researcher removes the estimate of 40 (say, due to an experimenter error).
Now we have the following estimates: 46, 30, 50, and 34.
We calculate the value of the mean. We get:
[tex]x=\frac{46+30+50+34}{4}\\\\x=\frac{160}{4}\\\\x=40\\[/tex]
We conclude that the value of the mean is 40.
