You have just received a report that specifies that the test statistic (2) is 1.35. In...
the test statistic of z=-1.35 is obtained when testing the claim that p=2/3 A) using a significance level of a=0.10, find the critical value(s)? B) should we reject Ho or should we fail to reject Ho? (round to two decimal places as needed. use a comma to separate answers as needed.)
Suppose that in a two-tail hypothesis test you calculate the value of the test statistic Z as -2.07, what is the p-value? Select one: 0.0192 0.0384 0.0197 0.9808 0.0096
Does training in study skills make a difference for student success? 8 students received training (M1= 85, SS1= 100) and 8 students did not (M2= 80, SS2= 124). Test using α = .05 Which is the null hypothesis, H0? µ1 = 0 µ1- µ2 ≠ 0 µ1- µ2 = 0 µ1 ≠ 0 The degrees of freedom (total) (df) = 18 14 16 10 With alpha = .05, (two tail, nondirectional test), the critical t score boundaries = +/- 2.145...
Write an APA style report that summarizes all of your findings. Your report should include each of the following, with no errors of APA style and formatting. Round p-values to three decimal places; all other measures to two. a) descriptive statistics for each trait in your sample, and for the population b) the value of the test statistic c) the precise p-value, ex. not p < .05 but p = .015, unless reports p = .000, in which case you...
You conduct a hypothesis test for the population mean. After you calculate the t test statistic, you find that your p-value = 0.04. Using alpha (a) = 0.01 level of significance, what is your decision regarding the null hypothesis? (either reject Ho and accept Ha, or fail to reject Ho)
Hi, I'm considering the following question: "Let's say we just calculated the t-test statistic for the following hypotheses: H0: mu <= 34, Ha: mu > 34. The sample size was 25, and the test statistic turned out to be -2.84. What would be the correct conclusion? A- Do not reject the H0 - the p-value is smaller than alpha B- Reject the H0 - the test statistic is more extreme than the critical value C- Reject the H0 - the...
Given a test statistic of 1.09, you are asked to perform a hypothesis test at the α = 0:05 level of significance for H0: p = 0.1 vs Ha: p =/= 0.1. Find the p-value for this test. A. 0.8622 B. 0.7242 C. 0.2758 D. 0.1379 E. 1.7244
The value obtained for the test statistic, z, in a one-mean 2-test is given. Whether the test is two tailed, left tailed, or right tailed is also specified. For parts (a) and (b). determine the P-value and decide whether, at the 1% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. a. The test statistic in a two-tailed test is z= -1.42. The P-value is (Round to three cocimal places as...
i need help with this question, please show work by hand no excel, spss thank you ! Assume you're using an alpha of 05, and a two-tailed test, to make your decision about whether to reject the null hypothesis. Assume that 18 subjects received one of three treatments and produced the data reported in Data Set B. Conduct a one-way ANOVA to see if the means of the three treatments are different on a statistically significant level. Complete an ANOVA...
Annual expenditures for prescription drugs was $838 per person in the Northeast of the country. A sample of 60 individuals in the Midwest showed a per person annual expenditure for prescription drugs of $745. Suppose the population standard deviation is $300. Follow the steps below to develop a hypothesis test to determine whether the sample data support the conclusion that the population annual expenditure for prescription drugs per person is lower in the Midwest than in the Northeast. 1. Formulate...
