onduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person purchased a slot machine and tested it by playing it 1,280 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observed outcomes agree with the expected frequencies, the author obtained a test statistic of χ2=8.187. Use a 0.05 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as expected? The test statistic is?

The researchers conducted a pretest to confirm that participants would repond differently to the emotional and rational groups. Participants in the pretest were asked to rate both groups (emotional, rational) on the scale ranging from 1 ( " cognitive, rational appeals would be more persuasive") to 5 ( " emotional, feeling-based appeals would be most persuasive "). A statistical analysis " indicated that participants believed that the group of scientists, mathematicians, and economic analysts would be more likely to be persuaded by cognitive appeals (M = 1.26, 95% CI = [ 1.16, 1.36 ]), whereas the group of artists, dancers, and musicians were thought more likely to be persuaded by emotional appeals ( M = 4.46, 95% CI = [ 4.31, 4.61]); t (49) = 15.24, p , .001, d = 2.16." Which statistical analysis did the researchers use to determine whether the results were statistically significant? a. Cohen's d b. Single sample t test c. Paired - sample t test d. Independent - samples t test
Suppose in a sample of 400 apples 79 are damaged You want to test the claim the proportion that are damaged is less than 20%. Hint There is strong evidence against H0 if the p-value is less than 0.05, alternatively there is strong evidence against H0 if the test stat is less than -1.645. Which option is the correct hypothesis test. Select one: a. H0: p= 0.8, H1 p> 0.8, standard error =10, test stat =0.5, p-value = 0.3084, reject H0 because there is strong evidence the proprotion is above 80% b. H0: p= 0.2, H1 p < 0.2, standard error =0.02 test stat =-0.125, p-value = 0.4503, do not reject H0 because there is not strong evidence the proprotion is less than 20% c. H0: p> 0.8 H1 p =0.8, test stat =-20 , p-value = 0.3084, do not reject H0 because there is strong evidence the proprotion is above 80% d. H0: =0.2, H1: < 0.2 , test stat =2.3, p-value = 0.01, do not reject H0 because there is not strong evidence the proprotion is above 80%
14% of all Americans suffer from sleep apnea. A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 391 people from the inner city surveyed, 59 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.05?
One private bank claims that they employ an average of 25 staff members at their branches. It was observed that this bank had an average of 20 employees with 3 employees in 15 randomly selected branches. Test the claim that the staff working in the branches of the bank employs less than 25 people on average at 1% meaning level.
A social worker in a certain city claimed that only 25% of the children between 19 and 35 months had not had all of their vaccines. You believe the percentage is higher. In order to test the social worker’s claim, you contact 145 families that have a child between 19 and 35 months and find that 44 of the children had not had all of their vaccines. Can the social worker’s claim be supported to a level of significance of α = .02, test the hypothesis.
For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) Researchers state 2.52.5 hours as the mean amount of television watched by children per night. One parent claims that the mean amount of television watched by children per night is less than 2.52.5 hours. The parent conducts a hypothesis test and rejects the null hypothesis. Assume that in reality, the mean amount of television watched by children per night is 2.52.5 hours. Was an error made? If so, what type?
Assume that a simple random sample has been selected and test the given claim. Use the P-value method for testing hypotheses. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. The ages of actresses when they won an acting award is summarized by the statistics nequals=7878, xequals=35.935.9 years, and sequals=11.411.4 years. Use a 0.050.05 significance level to test the claim that the mean age of actresses when they win an acting award is 3232 years. What are the hypotheses? A. Upper H 0H0: muμequals=3232 years Upper H 1H1: muμless than<3232 years B. Upper H 0H0: muμequals=3232 years Upper H 1H1: muμnot equals≠3232 years Your answer is correct. C. Upper H 0H0: muμequals=3232 years Upper H 1H1: muμgreater than or equals≥3232 years D. Upper H 0H0: muμnot equals≠3232 years Upper H 1H1: muμequals=3232 years Identify the test statistic.…
Suppose the dietician conducted his study and found a p-value of 0.085. Based on this p-value, what would you conclude? a. Fail to reject the null hypothesis since p > 0.05, conclude that there is a relationship between beverage preference and gender b. Reject the null hypothesis since p > 0.05, conclude that there is a relationship between beverage preference and gender c. Fail to reject the null hypothesis since p > 0.05, conclude that there is no relationship between beverage preference and gender d. Reject the null hypothesis since p > 0.05, conclude that there is no relationship between beverage preference and gender
USA Today reported results from an Arity survey in which 2018 drivers were asked if they text while driving. Among the respondents, 42% said that they text while driving. What is the exact value that is 42% of the number of respondents? Could the result from part (a) be the actual number of respondents who said that they text while driving? Why or why not? What is the actual number of respondents who said that they text while driving? What do the results suggest about highway safety?
A hypothesis test was performed to decide whether the mean number of words spoken per day by men is fewer than for women. αα = 0.05 and p = 0.02. If a man and a woman are randomly selected there is a 2% chance that the man will speak fewer words than the woman on that day.
A hypothesis test is performed in a study of AirBnB's to learn about the proportion of them that have 4 televisions. The null and alternative hypotheses are as followed: Null: p=0.13 Alternative: p<0.13 Researchers had determined that 39/500 randomly selected airbnb's had 4 televisions. Once all of the necessary conditions were verified for a statistical inference, the researchers correctly calculated the P-Value to be approximately 2.7269x10^-4 a) Please use the appropriate symbols and values to communicate the specific conditional probability that the P-Value represents in the context of this study. b) In a sentence or two, describe the specific event in the context of this study which has probability equal to the P-Value of occuring. c) When the P-Value in this hypothesis test is rounded and expressed with 3 digits after the decimal point (0.000) does it mean that the event described in part (b) has no chance of occurring? Explain in one to two sentences.
