Values are attached  a) Carefully define the null and alternative hypotheses of the ?2 test underlying the generation of the above table.  b) Find the missing values ‘*’, ‘**’, ‘***’, ‘??’ and ‘???’.  c) What is the conclusion of this test? Give reasons for your answer.

Identify null and alternative hypothesis In the study described above, the next weekend they took all 50 children and put them into groups based on their weight. Each child in the live action group was weighed and a second child in the same weight category was put in the cartoon group. The number of crackers were now assessed for all children.

Rock-paper-scissors is a hand game played by two or more people where players choose to sign either rock', paper', or scissors' with their hands. We would like to test if players choose between these three options randomly, or if certain options are favored above others. What hypothesis test should we conduct to answer this research question? O Compare two means O Chi square test of independence O Chi square test of goodness of fit O Compare two proportions

14)  A traffic-safety researcher is studying driver’s behavior (complete stop, coasting stop, ran stop sign) at a specific stop sign. The researcher would like to know if driver behavior depends on the type of vehicle (car, sport utility vehicle [SUV], pickup truck).   a) What is the appropriate null and alternate hypothesis to determine if stop sign behavior depends on type of vehicle?  b) The traffic-safety researcher observes 500 vehicles at the stop sign and records the two variables: the type of vehicle (car, sport utility vehicle [SUV], pickup truck) and the driver’s behavior at the stop sign (complete stop, coasting stop, ran stop sign).  The data appears below. Use JMP software to test the hypothesis of part a). c)  Using alpha= 0.05, draw a conclusion for the hypothesis test and state the conclusion in the context of the problem.   SUV stop Car stop Car coast Car coast SUV coast Car stop Car coast Car coast Car stop Pickup coast Car coast Car ran Car…

What is the correct interpretation of the significance level a in a hypothesis test? The probability that H, is true given that Ho is NOT rejected The probability that Ho is true given that Ho is rejected The probability of NOT rejecting Ho given that H, is true The probability of rejecting Ho given that Ho is true

When we examine a proposed experimental study for possible confounds, which of these should look for? Confounds due to the age of the participants the order in which the conditions of the study were tested the size of the sample whether the study has ever been carried out before and published (a and b), but not (c and d)

Perform a hypothesis test for a population mean and for a population proportion A group of psychologists commented that less than 57% of them help children to enjoy reading to improve their intelligence. An investigation was conducted to find out if this is true in a certain school zone. 210 psychologists were randomly chosen and interviewed to detect whether, by developing their work in psychology, they help children to enjoy reading to improve their intelligence; It was found that 105 psychologists do help children. Perform the hypothesis test with alpha of 10%.

A local chess club claims that the length of time to play a game has a mean of 23 minutes or more. Write sentences describing type I and type II errors for a hypothesis test of this claim.       A type I error will occur if the actual mean of the length of time to play a game is ▼   less than equal to less than or equal to greater than not equal to greater than or equal to 23 ​minutes, but you ▼   fail to reject reject the null​ hypothesis, ▼   Upper H 0 : mu less than 23H0: μ<23 Upper H 0 : mu equals 23H0: μ=23 Upper H 0 : mu not equals 23H0: μ≠23 Upper H 0 : mu less than or equals 23H0: μ≤23 Upper H 0 : mu greater than or equals 23H0: μ≥23 Upper H 0 : mu greater than 23H0: μ>23 .   A type II error will occur if the actual mean of the length of time to play a game is ▼   not equal to greater than or equal to equal to greater than less than or equal to less than 23 ​minutes, but you ▼   fail to reject reject the null​ hypothesis, ▼…
