Statistics help A test of hypothesis for Ho:p= 5 against H. :p 5 was conductedusing a statistical software. We do not have access to the data anymore, but only know the following from the computer output: teststatistic value =-0.96 and p-value =0,38. Based on this information,what would be the test statistic and p-value for testing Ho: µ = 5against H, p> 5 if we wereable to use the same data?

Given Population mean μ=5 Hypothesis Ho: μ=5 vs H1: μ≠5(Two tailed) Test statistic =-0.96, p…

Are seatbelts effective at saving lives? We wish to examine whether or not the use of seatbelts reduces fatalities at the alpha = 0.05 level of significance. Let p N represent the proportion of non-seatbelt wearing passengers who were involved in a crash and died and represent the proportion of seatbelt wearing passengers who were involved in a crash and died. 1. Which would be correct hypotheses for this test?

Consider the following: In general, when people diet they typically lose 10 lbs. (?σ = 2). A random sample of 16 people on the keto diet lost 15 lbs. Do people on the keto diet lose more or less weight than people on diets in general? 3. What is the Null Hypothesis? a)On average, weight loss in the keto diet sample does not differ from weight loss in the population of dieters in general. (H0: X-bar = Mu)) b)On average, weight loss in the keto diet sample does not differ from weight loss in the population of dieters in general. (H0: X-bar does not equal Mu) c)On average, weight loss in the keto diet sample differs from weight loss in the population of dieters in general. (H0: X-bar does not equal Mu) d)On average, weight loss in the keto diet sample differs from weight loss in the population of dieters in general. (H0: X-bar = Mu)

Using the information provided in the SPSS output. You are asked to make a decision about whether to reject the null hypothesis that the population value of gamma equals 0 (i.e., that there is no ordinary association in the population between frequency of prayer and health). If alpha = 0.05 and you use a non-directional alternative hypothesis, which of the following is true?) A. Since the p-value is larger than alpha, you do not reject the null hypothesis B. Since the p-value is less than alpha, you do not reject the null hypothesis C. Since the p-value is larger than alpha, you reject the null hypothesis. D. Since the p-value is less than alpha, you reject the null hypothesis
A nationwide study of undergraduate students reported that the mean number of drinks consumed per week during the spring semester is 7.96. The mean number of drinks consumed per week at USC is 7.64 (s.d.=2.55, N=412 Health services is concerned that USC students are consuming significantly more alcohol per week than the national average. Using an alpha level of .05, Is there sufficient evidence to be concerned? Be sure to select the correct critical value for the alternative hypothesis, and then use this evidence to make your conclusion
The test statistic z=1.42 is obtained when testing the claim that p>4 a) find the p value B) using a significance level that alpha =0.01, should we reject the null hypothesis or fail to reject the null hypothesis
Match the p-values with the appropriate conclusion: I. 0.00001 II. 0.0189 III. 0.0611 IV. 0.4234(a) The evidence against the null hypothesis is significant, but only at the 10% level. (b) The evidence against the null and in favor of the alternative is very strong. (c) There is not enough evidence to reject the null hypothesis, even at the 10% level. (d) The result is significant at a 5% level but not at a 1% level.
In a completely randomized experimental design, three brands of paper towels were tested for their ability to absorb water. Equal-size towels were used, with four sections of towels tested per brand.

In my regression output using Hayes Model 1 I have the following results. Would it be safe to say that the following assumption is correct? 95% CI is [.036, .196] not statistically significant, But given that (p = .176) is greater than p=.005, we reject the null hypothesis. (b3) of .080, t = 1.36, p = .176, 95% CI [.036, .196].
A sample of n=25n=25 data values randomly collected from a normally distributed population has standard deviation s=2.1s=2.1. We wish to test the null hypothesis H0:σ=1.5H0:σ=1.5 against the alternative hypothesis H1:σ>1.5H1:σ>1.5 at a significance of α=0.01α=0.01. What is the value of the test statistic? Write your answer rounded to 3 decimal places. What is the critical value? Write your answer rounded to 3 decimal places.
