A Fun-Size bag of M&M's contains 5 green, 4 red, 3 yellow, 6 orange, 4 blue, and 2 brown candies. Construct a relative frequency table of the results. Use two decimal places in your relative frequencies. Color Proportion Green i Red i Yellow i Orange Blue i Brown Total 1.00

. State the interval estimate that contains more possible values of the population mean (precision) for a 90% CI or a 95% CI for the same data.

Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 5 females and 5 males and measured their MRI image pixel counts and IQ scores. Females Males MRI IQ MRI IG The data is reported to the right.

Are MRI count and IQ linearly related? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Round to three decimal places as needed.) A. Yes, MRI count and IQ are linearly related since the linear correlation coefficient is O B. No. MRI count and IQ are not…
