To find out best estimates for the mean and standard deviation of the
Answer to Problem 6PT1
The option c) is correct
Explanation of Solution
Since normal density curve is symmetrical about mean, the middle value on x-axis about which curve is symmetrical is found. For this, a perpendicular from the peak of the curve is drawn which cut x-axis at
Therefore, the best estimates for the mean and standard deviation of the normal distribution are-
Thus, answer is option (c).
