Show at least one computation using Welch’s T Test and at least one computation using the 2-Sample T Test for Equal Means. The Problem: Members of the Town of Colonie Golfers' Loop frequentlyraise concerns to Mr. Lange, as its leader, about how the league is run. Themost frequent concern raised is that the teams competing each week are notstatistically even. In other words, members raise concerns that one or moreteams have a statistical advantage over other teams.To evaluate the validity of these claims, Mr. Lange has decided to use a mixof statistical hypothesis tests discussed in this course to evaluate the teamsfrom Outing #14 in calendar-year 2016 (2016, #14). One is the Equal Vari-ances F Test, one is Welch's T Test, and the other is the 2-Sample T Testfor Equal Means.In this particular outing, seven teams were competing for the win. A randomsample of eight prior scores from each team member was collected, and thesummary statistics are shown below (correct to three decimal places).Team Sample Size Sample Mean | Sample Variance12423233245673232323276.50079.65679.50082.37580.40680.28180.438To test for statistical evenness among these teams using the mix of tests wedescribed above, however, we will have to adjust the significance levels weare accustomed to using.

A computer company wants to determine if there is a difference in the proportion of defective computer chips in a day’s production from two different production plants, A and B. A quality control specialist takes a random sample of 100 chips from the first hour of production from plant A and determines that there are 12 defective chips. The specialist then takes a random sample of 100 chips from the last hour of production from plant B and determines that there are 10 defective chips. Assuming conditions for inference are met, what is the 90% confidence interval for the true difference in proportions of defective chips from a day’s production between the two plants? Find the z-table here.

In an efiort co counteract student cheating, the professor of a large class created four versions of a midterm exam, distributing the four versions among the 312 students in the class. After the exam, 6 students from the class got together and petitioned to nullify the results equal in difficulty. the grounds that the four versions were not To investigate the students' assertion, the professor examined the means and variances of the scores on the different versions of the exam, obtaining the following information (the exam had 200 possible points). Sample Sample Sample size Group mean variance Version A 78 154.2 393.3 Aa Version B 78 149.3 333.7 Version C 78 151.6 468.5 Version D 78 154.0 415.0 Send data to calculator Send data to Excel Taking the 78 scores for each version of the exam as a sample of scores for that version, the professor performed a one-way, independent-samples ANOVA test of the equality of the population mean scores for the four versions. Answer the following,…

This is the question for the second picture 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.

Suppose 40 participants complete an experiment whero ads are presented subliminally during a task) ads are at very fast rates during movie ads)Participants are then given a recognition test of images of the ads, where two images are presented and participants must choose which of the two was presented earlierBoth men and women (20 of each gender) participate in the study and the researcher predicts that the recognition accuracy will offer across gender. The difference between the sample means in this study was 5%. The for the men was 350 and the the women was 250. What is your t value? A) 3 B) 4.69 C) 3.54 D) 4
In a particular DNA region of 1200 bases the following counts of each of these bases was observed: A - 333, C - 255, G - 297, T - 315. A scientist believes that in this region the probability of observing an A is equal to the probability of observing a T and they are both 0.3, and the probability of observing a C is equal to the probability of observing a G and they are both 0.2. Perform a chi-squared goodness-of-fit test to test the null hypothesis that there is no significant difference between the observed data and the proposed model versus the alternative that the data differs significantly from the proposed model. What is your conclusion at the a= 0.1 level and what is the p-value of this test?
A random sample of 200 middle school students was collected and the students were asked the question, "If you could have only one type of pet, what would it be?” The responses, separated by grade, are shown in the table. A teacher wants to perform a chi-square test of independence/association on the data. Are the conditions for such a test met? A. Yes, the sample size of 200 is large B. Yes, all the expected cell counts are 5 or higher. C. Yes, all the observed cell counts are 5 or higher. D. No, not all the observed counts are above 5. E. No, some of the expected cell counts are below 5.
a) Seven puppies were born in a litter, and it is determined whether each puppy is male or female. How many outcomes exist in the above experiment? b) Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 25 bank accounts, we want to take a random sample of six accounts in order to learn about the population. *How many different random samples of six accounts are possible?
