If the standard deviation of hole diameter exceeds 0.01 millimeters, there is an unacceptably high probability that the rivet will not fit. Suppose that n = 15 and s = 0.008 millimeter. Is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeter? Use a = 0.01 O a. Test on Mean, Variance Known O b. Test on Variance and Standard Deviation O. Test on Population Proportion O d. Test on Mean, Variance Unknown

Use Table A to find the value z of a standard Normal variable that satisfies each of the given conditions. (Use the value of z from Table A that comes closest to satisfying the condition.) In each case, sketch a standard Normal curve with your value of z marked on the axis. Find the point z with 14% of the observations falling below it. Give your answer to two decimal places.

Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of u-23.3 in. and a standard deviation of a 1.2 in. These data are often used in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high Pix or greater) s0.01 and a value is significantly low if P(x or less) 50.01. Find the back-to-knee lengths separating significant values from those that are not significant. Using these criteria, is a back-to-knee length of 25.4 in. significantly high? Find the back-to-knee lengths separating significant values from those that are not significant Back-to-knee lengths greater than in and less than in are not significant, and values outside that range are considered significant (Round to one decimal place as needed.)

I am having difficulty with The Analysis of Biological Data chapter 10 question 15AP, I need to check my solutions but there are none posted for me to review. If I could compare answers that would be great.

A survey found that women's heights are normally distributed with mean 62.8 in. and standard deviation 2.2 in. The survey also found that men's heights are normally distributed with mean 69.5 in. and standard deviation 3.2 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 56 in. and a maximum of 63 in. Complete parts (a) and (b) below. a. Find the percentage of men meeting the height requirement. What does the result suggest about the genders of the people who are employed as characters at the amusement park? The percentage of men who meet the height requirement is %. (Round to two decimal places as needed.)

It is given that a vending machine dispenses a mean of 7.6 ounces with a standard deviation of 0.4 ounce. For the vending machine to overflow an 8-ounce cup, the machine must pour more than  8 − 7.6 =   ounces greater than the mean. This amount is   standard deviation(s) from the mean.

What is the formula for the standard error of the normal approximation to the p distribution. P=
