I am struggling in my Psyc 300 Statistic class. I seem to have missed a concept early in our class and now the following homework problem has left me lost. One Sample t-test 1. A professor wants to know whether her students’ GPAs differ from the entire student population at the University ( She records 20 of her students’ GPAs and compares the mean ( = 3.25, sd = 0.85) to the population, predicting that her students will have different GPAs than the University population. Using an alpha of .05, perform an appropriate t- test. Hypothesis: tthreshold= df = tobs = Conclusion:

You take a survey that is supposed to measure whether you are an extrovert or not. The score you get on the extrovert survey is a z-score of 2.0. What does that mean about your level of extraversion compared to the average score?
The data below are from a sensory deprivation study looking at hearing threshold before and after one hour in a sensory deprivation chamber. Seven subjects had their hearing checked both before and after they were in a dark, silent chamber. Hearing threshold is the minimum sound level you can detect. Test the hypothesis that hearing should be more sensitive (thus lower numbers) after sensory deprivation compared with before (use alpha = .05). BEFORE: 11, 34, 18, 33, 35, 22, 35 AFTER: 13, 31, 18, 29, 32, 20, 28 What is the design of this study? What is the independent variable? What is the dependent variable? n = people Is the hypothesis one-tailed or two-tailed? State the Hypotheses in symbols and words: in words: Hị: in words: Create an Excel data file organized by rows. Each row is a participant. Variables – Before, After Open this dataset in JASP.

A study was done to look at the relationship between number of lovers college students have had in their lifetimes and their GPAs. The results of the survey are shown below. Lovers 0 3 1 2 5 1 8 GPA 3.3 2.9 3.4 3.3 2.5 2.8 0.7 1. The p-value is: _____ (Round to four decimal places) 2. Use a level of significance of α=0.05 to state the conclusion of the hypothesis test in the context of the study (pick one). a. There is statistically significant evidence to conclude that there is a correlation between the number of lovers students have had in their lifetimes and their GPA. Thus, the regression line is useful. b. There is statistically significant evidence to conclude that a student who has had more lovers will have a lower GPA than a student who has had fewer lovers. c. There is statistically insignificant evidence to conclude that a student who has had more lovers will have a lower GPA than a student who has had fewer lovers. d. There is statistically insignificant…
p 15 Is sunscreen with an SPF 30 rating more effective at preventing sunburn than sunscreen with an SPF 15 rating? At the alpha = 0.05 level of significance, test the claim that SPF 30 sunscreen is better at preventing sunburn than 15 sunscreen. Let represent the proportion of SPF 15 sunscreen wearers who get a sunburn and represent the proportion of SPF 30 sunscreen wearers who get a sunburn. (Round your results to three decimal places) 1. Which would be correct hypotheses for this test? O O H 0 :p 15 =p 30 , H 1 :p 15 ne p 30 H 0 :p 15 =p 30 , H H 1 :p 15 <p 30 O H 0 :p 15 <p 30 ,H 1 :p 15 >p 30 O H 0 :p 15 =p 30 H 1 :p 15 >p 30 A random sample of 250 beach-goers were given SPF 15 sunscreen and asked to lay in the sun for 1 hour10 of them later reported a sunburn. Another random sample of 250 beach- goers were given SPF 30 sunscreen and asked to lay in the sun for 1 hour. 7 of them later reported a sunburn. 2.Find the test statistic 3.

MORE BENEFITS OF EATING ORGANIC Using specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data. In this case, we are testing Họ : Po = Pc Ha: Po > Pc where p, and p. represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. Use a 5 % significance level. Effect of Organic Bananas After 25 Days After 25 days, the proportion of fruit flies eating organic bananas still alive is 0.45 , while the proportion still alive eating conventional bananas is 0.42. The standard error for the difference in proportions is 0.029. What is the value of the test statistic? Round your answer to two decimal places. z = i What is the p-value? Round your answer to three decimal places. p-value = What…
Hi, i have one question. How was the level of significance obtained? at the beginning of the exercise it is clarified that it is (α)=0.05 but I don't know where this value comes from
You are conducting a test of independence to see if getting the flu is independent of whether or not you got a flu shot. Use a = 0.05. Report all answers accurate to four decimal places. Here is the sample data. Category Got Flu Shot Did not get Flu Shot Category Got Flu Shot The expected observations for this table would be: Got the Flu Did not get Flu Shot The resulting (O - E)² E Got the Flu 18 51 Category Got Flu Shot Did not get Flu Shot Did not get the Flu 118 19 Got the Flu for finding the test are: Did not get the Flu What is the p-value for this test-statistic? P-Value = Did not get the Flu What is the chi-square test-statistic for this data? (add the results from the previous table) x² =
ACT scores range from 1 to 36 and are normally distributed where N (21.5, 5.4). SAT scores• range from 600 to 2400 and are normally distributed where N (1498, 316). Jorge scores 2090 on the SAT. If both tests measure the same thing, what score on the ACT is equivalent to Jorge's SAT score?
