Arecent study by a major financial investment company was interested in determining whether the annual percentage change in stock price for companies is linearly related with the annual percent change in profits for the company. the following data was determined for 7 randomly selected companies: col1 % change stock price (y) 8.4 9.5 13.6 -3.2 7 18.4 -2.1col2 % change in profit (x) 4.2 5.6 11.2 4.5 12.2 12 -13.4 based upon this sample information, which of the following is the regression equation? a. y? 1.19-3.00 x b· y? =-4.198-0.612x c. y? =+4.198 x d, y? = 4.198 + 0.612 x

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?

(x-5)1/2+5=2 what is a possible solution?

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
