A sample of 30 NBA players are randomly collected. Their average height is 73.7 inches with a standard deviation of 2.2917. Their average age is 28.498 years old with a standard deviation of 3.8617. Their average weight is 204.13lbs with a standard deviation of 21.0954. I need help with a) and d)! a) verify that your samples satisfies the Central Limit Theorem for height, weight, and age.

b) Construct a 90% confidence interval specified by hand for each

height: 73 inches to 74.4 margin of error: .685

age: 27.3 to 29.7 margin of error: 1.16

weight: 198 to 210 margin of error: 6.34

c) Construct a 99% confidence interval by hand for each

weight: 194 to 214 margin of error: 9.92

height: 72.6 to 74.8 inches margin of error: 1.08

age: 26.7 to 30.3 margin of error: 1.82

d) Give a brief explanation about the difference between the level of confidence and how it affects your interval.

Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.

Which inequalities can be used to find the solution set of the following inequality? check all that apply. |2x – 5| (2x – 5) (2x + 5) –(2x – 5) –(2x + 5)

Ican interpret and represent the remainder in division calculations sensibly for the context (eg 27.4 in calculating average height in cm: $27.44 if it represents an amount of money) solve the following problems. 15) the wildlife park charges $25.50 dollars per person to enter their park if the park made $15096 dollars today, how many people entered the park? 16) ms adams plus 2,230 other keen runners ran a marathon: between them they ran 94817.5km. how many km did each competitor run?
