Select the correct answer. Charlie gathered data about the time it takes him to complete a crossword puzzle and the number of clues in the puzzle. He used a
graphing tool to organize the data in a scatter plot and find the line of best fit.
He found the relationship between the number of clues, x, and the time required to complete the puzzle, y, is modeled by the equation
y=0.376x + 15.48, and the correlation coefficient for the data is 0.219.
Could the line of best fit be used to make reliable predictions about the time it takes Charlie to complete a crossword puzzle?
O
Yes, because the slope of the line of best fit is closer to o than to 1, which indicates a strong association between the
variables.
O
Yes, because the correlation coefficient is closer to o than to 1, which indicates a strong association between the
variables
No, because the slope of the line of best fit is closer to 0 than to 1, which indicates a weak association between the
variables.
No, because the correlation coefficient is closer to o than to 1, which indicates a weak association between the variables.

Thompson and thompson is a steel bolts manufacturing company. their current steel bolts have a mean diameter of 127 millimeters, and a variance of 36. if a random sample of 35 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 0.5 millimeters? round your answer to four decimal places.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
