**Problem 6: Mint Weight Distribution Analysis**A candy maker produces mints with a labeled weight of 20.4 grams. The actual distribution of the weights follows a normal distribution with parameters \(N(21.37, 0.16)\).**a) Single Mint Probability Calculation**Let \(X\) be the weight of a single mint chosen randomly from the production line. We seek the probability that this mint weighs more than 22.07 grams, denoted by \(P(X > 22.07)\).**b) Multiple Mints Probability Calculation**Consider a scenario where 15 mints are selected independently and weighed. Let \(Y\) represent the count of these mints that have a weight less than 20.8 grams. We are tasked with finding the probability that at most 2 of these mints weigh less than 20.8 grams, expressed as \(P(Y \leq 2)\).

Question 6)The distribution of the weights of mints is .a. The random variable represents the…

Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation.
