Post by: jk56 on Mar 10, 2018 A manufacturer of power tools claims that the mean amount of time required to assemble their top-of-the-line table saw is 80 minutes with a standard deviation of 40 minutes. Suppose a random sample of 64 purchasers of this table saw is taken. The standard deviation of the sampling distribution of the sample mean is ________ minutes.
Fill in the blank(s) with correct word Q. 2 If a data set is approximately normally distributed, its normal probability plot would be S-shaped. Indicate whether the statement is true or false Q. 3 A manufacturer of power tools claims that the mean amount of time required to assemble their top-of-the-line table saw is 80 minutes with a standard deviation of 40 minutes. Suppose a random sample of 64 purchasers of this table saw is taken. The mean of the sampling distribution of the sample mean is ________ minutes. Fill in the blank(s) with correct word Q. 4 A normal probability plot may be used to assess the assumption of normality for a particular set of data. Indicate whether the statement is true or false Q. 5 The amount of bleach a machine pours into bottles has a mean of 36 oz. with a standard deviation of 0.15 oz. Suppose we take a random sample of 36 bottles filled by this machine. So, the middle 95 of the sample means based on sample sizes of 36 will be between ________ and ________. Fill in the blank(s) with correct word Q. 6 The middle spread, that is the middle 50 of the normal distribution, is equal to one standard deviation.
