9. The time (in seconds) required to catch a falling meter stick was recorded for 6 randomly selected students, both using their dominant hand and non-dominant hand. The data are shown below: Student Dominant Non-dominant 1 2 3 4 5 6 0.177 0.210 0.186 0.189 0.194 0.198 0.179 0.202 0.208 0.184 0.215 0.193 Using a=0.10, test whether the dominant hand time is faster than the non-dominant hand time. You may assume that all conditions are satisfied.

Solve the following problem. Show your complete solution. 2. Joe, a DOH COVID-19 tracker, found out that the number of infected persons of COVID-19 in seven low-risk provinces of the country are 1, 9, 2, 12, 8, 7, and 10. Suppose that 5 provinces are drawn as sample. a.) What is the mean (?), variance (?2) and standard deviation of the population (σ)? b.) How many different samples of size n =5 can be drawn from the population? List them with their corresponding mean. c.) Construct the sampling distribution of the sample mean.

Perform an independent-measures (samples) t-test in SPSS to determine if the starting salary (Variable "salary" "Starting Salary") of males is significantly higher than the starting salary of females. Use α = .01. p-value .0005 T-statistics 3.45 This is a one-tailed test because we are interested in whether the salary of one group is significantly greater than the salary of the other group Our assumption is this correct ? We reject the null because because .0005 is less than .01 and conclude male salary is greater than female salary ? or it is not greater ?
At ABC College it is estimated that at most 10% of the students use public transportation to the college. Does it seem to be a valid estimate if, in a random sample of 120 students, 25 students use public transportation. (Use α = .01)
Suppose a random sample of n=60 college students were surveyed and r=11 of them said that blue is their favorite color. Use a=0.05. What is the value of the sample test statistic? 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.
Complete both tables on the remaining pages and show your work for at least three Equal Variances F Tests and at least five T tests. You must show at least one computation using Welch’s T Test and at least one computation using the 2-Sample T Test for Equal Means.(I don't know how to find the distribution or probability for the first chart)
