Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (Each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) Results from five of the students are included in the graph to the right. Use a 0.02 significance level to test the claim that there is no difference between the reaction times of the right and left hands. LOADING... Click the icon to view the reaction time data table.

For a population with u = 84 and o = 4, what is the z-score corresponding to X= 80? O -1,00 +1,00 O+1.25 -1.50
Participants threw darts at a target. In one condition, they used their preferredhand; in the other condition, they used their other hand. All subjects performed inboth conditions (the order of conditions was counterbalanced). Their scores areshown below.Preferred Non-preferred12 77 911 813 1010 9a. Which kind of t-test should be used?b. Calculate the two-tailed t and p values using this t test.c. Calculate the one-tailed t and p values using this t test.
Which of the following statements correctly describes the effect of increasing the alpha level (for example, from a = .01 to a = 05)? This action increases the likelihood of rejecting Ho and increases the risk of a Type I error. This action decreases the likelihood of rejecting Ho and increases the risk of a Type I error. o This action increases the likelihood of rejecting Ho and increases the risk of a Type Il error. O This action decreases the likelihood of rejecting Ho and increases the risk of a Type Il error.
A left-tailed z-test found a test statistic of z = -1.99. At a 5% level of significance, what would the correct decision be? Question 20 options: Do not reject H0 Do not reject H1 Accept H0 Reject H1 Reject H0
The degrees of freedom is critical to computing the p-value for the chi-square goodness of fit. We will discuss the p-value in the next lab. The degrees of freedom for the Chi-Square goodness of fit is equal to (the number of non-zero rows in the table) - 1. The number of non-zero rows is the number of expected values that are non-zero. For example: Phenotype ... Expected ... Disease ... 234 ... Wild-type ... 6743 ... has two rows where the Expected value is non-zero. So the degrees of freedom is 2-1 = 1. Another example: Phenotype ... Expected ... Disease ... 2374 ... Wild-type ... 0 ... has one row where the Expected value is non-zero. So the degrees of freedom is 1-1 = 0. With 0 degrees of freedom, the chi-square test cannot be calculated. A third example (sex-linked): Phenotype ... Expected ... Disease-Male ... 2374 ... Disease-Female ... 9456 Wild-type-Male ... 1001 ... Wild-type-Female ... 235 ... has four rows where the Expected values are…

Find the p value. 80% of all supermarketsprices end in the digit 9 or 5. Suppose a random sample of 116 items in a suoermarket find that 87 have prices that end in 9 or 5. Use a=0.05. What is the value of the sample test statistic? Find the p value.
