Explanation of Solution
In the question, it is given that the distribution of seed weights for a variety of winged bean. This distribution is approximately Normal with,
And we are considering selecting at random four seeds of this variety. Thus, theprobability that all four seeds in the sample weighs more than
And the probability that the average weight of the four seeds is greater than
By looking at the above two probabilities we can see that the probability that all four seeds in the sample weighs more than

Answer to Problem 16.26AT
The probability that all four seeds in the sample weighs between
Explanation of Solution
In the question, it is given that the distribution of seed weights for a variety of winged bean. This distribution is approximately Normal with,
And we are considering selecting at random four seeds of this variety. Thus, the probability that all four seeds in the sample weighs between
And the probability that the average weight of the four seeds is between
Both of these probabilities are smaller relative to the corresponding answer from part (b). Since the probability an individual seed weighs between

What is the 95% confidence interval of this mean difference?arrow_forwardIn order to find probability, you can use this formula in Microsoft Excel: The best way to understand and solve these problems is by first drawing a bell curve and marking key points such as x, the mean, and the areas of interest. Once marked on the bell curve, figure out what calculations are needed to find the area of interest. =NORM.DIST(x, Mean, Standard Dev., TRUE). When the question mentions “greater than” you may have to subtract your answer from 1. When the question mentions “between (two values)”, you need to do separate calculation for both values and then subtract their results to get the answer. 1. Compute the probability of a value between 44.0 and 55.0. (The question requires finding probability value between 44 and 55. Solve it in 3 steps. In the first step, use the above formula and x = 44, calculate probability value. In the second step repeat the first step with the only difference that x=55. In the third step, subtract the answer of the first part from the…arrow_forward
