Time taken by a randomly selected applicant for a mortgage to fill out a certain form has a normal distribution with mean value 10 min and standard deviation 4 min. If fiveindividuals fill out a form on one day and six on another, what is the probability that the sample average amount of time taken on each day is at most 11 min? (Round your answerto four decimal places.)USE SALT0.9802xYou may need to use the appropriate table in the Appendix of Tables to answer this question.

To solve this problem, we will use the properties of the normal distribution and the central limit…

A right skewed data set has a mean of 35 and a standard deviation of 25. What can be said about the amount of data contained within the interval (-15, 85)? 95% of the data is within this range 68% of the data is within this range Nothing At least 75% of data is within this range
This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here.
