The ordinary student goes through 500 unnecessary cups in a year. To raise natural care, an understudy pack at a tremendous school chose for help count the quantity of cups were used by understudies on their grounds. An unpredictable illustration of 50 understudies' results found that they used a mean of 476 cups with a standard deviation = 42cups, at a = 0.01, is there satisfactory evidence to reason that the mean differs from 500?

The prescription name on a particular medicine recommends 90 - 130 mg of the drug per kilogram of body weight every day. An expert underwrites 300 mg of the prescription predictably for a 25-pound adolescent. Is the arrangement inside the standards? Work ought to be shown using the unit change equivalences from the tables in the course book. Answers will fuse authentic units and will be changed in accordance with two decimal spots.

a. Convert 25 pounds to kilograms.

b. Find the proposed proportion of the prescription (in mg) every day for a 25-pound kid.

c. Find the proportion of the medicine supported every day.

d. Is the arrangement inside the standards? (Does your answer from (c) fit inside your arrive at answer from (b)?)

Zero in on what it says in striking. Watch sentence structure, remember about words, highlight as well. Much gratitude to you.

The substance of an exchange of 1200 tins

of a thing have a mean mass of 0.504 kg

likewise, a standard deviation of 92 g. Choose the probability that a subjective model

''8''

of 40 tins drawn from the exchange

will have a united mass of (a) not actually

20.13 kg, (b) between 20.13 kg and 20.17 kg,

likewise, (c) more than 20.17 kg, right to three

A game show contender is offered the decision of getting a PC structure worth $2300 or enduring a chance to win either a luxury trip worth $4300 or a boat worth $7800. In case the resulting decision is picked the competitor's probabilities of winning the outing or the boat are 0.20 and 0.15, exclusively. If the competitor were to turn down the PC structure and go for one of various prizes, what may be the ordinary prizes?

The ordinary prizes are ___________

Consider the going with statement to answer parts a, b, and c.

Question 5: Prove the following two properties of the fitted (via least-squares) simple linear regression model in Question 4: n in yi i i=1 i=1 and n M Diei = 0 i=11. Whv is the F statistic alwavs positive? 2. 1|.I'||.ihen is an analysis of variance [AN OVA] a more appropriate test to use than a t-test? 3. 1I.I'tih1..l'is multiple regression often more useful than simple linear regression? 4. A metaanalysis found a negative correlation between birth weight and blood pressure later in life. a. Explain what is meant by a negative correlation between these to variables. b. If vou were to examine these two variables with simple linear regression instead of correlation, how would vou frame the question? {hint the research question for the conelation would be: is birth weight related to blood pressure?) c. 1|.I'||.ihat is the difference between simple linear regression and multiple regression? d. If vou were to conduct a multiple regression instead of a simple linear regression, what other predictor variables might you include? 3. Interpolation and approximation. Describe in detail how to use Lagrange interpolation polynomials and divided differences to compute interpolation polynomials p() of degree
