28. Bone Length Research performed at NASA, led by Dr. Emily R. Morey-Holton, measured the lengths of the right humerus and right tibia in 11 rats that were sent to space on Spacelab Life Sciences 2. The data on page 175 were collected. (a) Draw a scatter diagram of the data treating length of the right humerus as the independent variable. (b) Based on the scatter diagram, do you think that there is a linear relation between the length of the right humerus and the length of the right tibia? (c) Use a graphing utility to find the line of best fit relating length of the right humerus and length of the right tibia. (d) Predict the length of the right tibia on a rat whose right humerus is 26.5 millimeters (mm). Right Humerus (mm), x Right Tibia (mm), y 24.80 36.05 24.59 35.57 24.59 35.57 24.29 34.58 23.81 34.20 24.87 34.73 25.90 37.38 26.11 37.96 26.63 37.46 26.31 37.75 26.84 38.50 Source: NASA Life Sciences Data Archive

Create a Scatterplot of y against average freshman high school GPA.

Please see attached image. I need to calculate a weighted moving average where the weights should be 0.2, 0.3, and 0.5.

Hi can you fill out the blanks for me?

Assume the cholesterol levels of an adult can be described by a Normal model with a mean of 183 ​mg/dL and a standard deviation of 27. Complete parts a through e.   ​b) What percent of adults do you expect to have cholesterol levels over 190 ​mg/dL?   enter your response here   ​% ​(Round to two decimal places as​ needed.) Part 3 ​c) What percent of adults do you expect to have cholesterol levels between 150 and 160 ​mg/dL?   enter your response here   ​% ​(Round to two decimal places as​ needed.) Part 4 ​d) Estimate the interquartile range of cholesterol levels.   IQR=enter your response here   ​mg/dL ​(Round to the nearest integer as​ needed.) Part 5 ​e) Above what value are the highest​ 15% of​ adults' cholesterol​ levels?   enter your response here   ​mg/dL ​(Round to the nearest integer as​ needed.)

Can someone please help? Thank you.

Don't do the cross(x) part of the question do the rest  g, a and b please do the calculation by hand so I can understand them tha
