Our group is trying to develop a study to see if watching a youtube video of a massage therapist helps viewers to feel more relaxed, specifically in the areas being massaged (head, neck, shoulders). Viewers will watch a video with sound, a video without sound (but with subtitles). -What would be H0 and H1

Are freshmen psychology majors less likely to change their major before they graduate compared to freshmen business majors? 355 of the 641 freshmen psychology majors from a recent study changed their major before they graduated and 404 of the 674 freshmen business majors changed their major before they graduated. What can be concluded at the = 0.05 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer H1: Select an answer Select an answer Select an answer Select an answer Select an answer (please enter a decimal) (Please enter a decimal) b. The test statistic ? C c. The p-value = d. The p-value is ? Q e. Based on this, we should Select an answer the null hypothesis. f. Thus, the final conclusion is that ... (please show your answer to 3 decimal places.) > Next Question (Please show your answer to 4 decimal places.) O The results are statistically insignificant at a = 0.05, so there is statistically…

The type of hypothesis test conducted (one-sample t-test, independent-measures t-test, or dependent-measures t-test)         The results indicated that college students’ attitudes towards alcohol consumption did not become less favorable following a month-long anti - binge drinking campaign (M = 3.56, SD = 1.05), t (27) = 1.35, p > .05.

An auto shop wants to examine the proportion of customers that have to return after an appointment. Last year, an examination of 381 customers found that 33.0% had to return after an appointment. You instituted some changes at the auto shop this year, and found from a sample of 258 customers that 36.2% had to return after an appointment. You want to conduct a hypothesis test to determine if there has been an increase in the proportion of customers that need to return after an appointment since the past year, with a = 0. 10. Using this information, what is the p in your analysis? Round your final answer to two decimal places. Note: 1- Enter your final answer with 2 decimal places.

A double-blind study was conducted to study the effectiveness and safety of the drug temazepam as a treatment for insomnia. 55 patients with diagnosed insomnia were randomly assigned to take one of two pills at bedtime: 26 patients took a placebo for 4 consecutive nights, 29 patients took 30 mg of temazepam for 4 consecutive nights. All patients completed sleep questionnaires following the 4th night. (a) What is the hypothesis of the study? O Patients who take a placebo will not get any sleep that night. O 30 mg of temazepam is an effective and safe drug for treating insomnia. O Many people have chronic insomnia. OA study determining the effectiveness of a drug must be a double-blind survey. O Temazepam is a good drug for anyone having trouble falling asleep. (b) The control group consists of [Select an answer (c) The experimental group consists of Select an answer

What is the null hypothesis?

Please help me better understand how to properly solve. A randomized controlled experiment in Charlotte, North Carolina, studied three police responses to spousal abuse: advise and possibly separate the couple, issue a citation to the offender, and arrest the offender. The effectiveness of the three responses was determined by re-arrest rates. The photo shows the rates.   Research wishes to test null hypothesis that that the proportions of subsequent arrests are the same regardless of the treatment assigned. Under the null hypothesis, determine the expected number of times no subsequent arrest would occur for the treatment “Advise/separate”?

Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up rejecting the null hypothesis in error.   True False

A group of 250 patients was randomly split into two groups of 125 patients. The first group of 125 patients was given treatment A, and 72 of them improved their condition. The second group of 125 patients was given treatment B, and 60 of them improved their condition. Perform a hypothesis test to investigate whether there is evidence of a difference between the two treatments. What is the p-value of the test?

A legal researcher was interrested in gender differences in the willingness of prosecutrs to plea bargain. She recorded the number of times they plea bargained out of their last 10 cases for a sample of eight female prosecutors and seven male prosecutors. Table 2 shows the number of plea bargain cases by gender.   Females Males     9 4     3 5     5 7     9 4     9 3     5 4     7 3     5     From performing a hypothesis test to determine if female and male prosecutors differ in their plea bargaining of cases what is the p value?
