Use technology to find the P-value for the following values of the test statistic t, sample size n, and alternate hypothesis H,. t= 1.535, n= 15, H;:µ#40

Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher wants to know if people find baby animals cuter than adult animals. All of the participants in a study are shown 10 pictures of baby animals and 10 pictures of adult animals. They are asked to rate (on a 1 to 10 scale) how cute they think each animal is.

Suppose that you want to perform a hypothesis test for a population mean. Assume that the population standard deviation is unknown and that the sample size is relatively small. In each​ part, the distribution shape of the variable under consideration is given. Decide whether you would use the​ t-test, the Wilcoxon​ signed-rank test, or neither.   a. Triangular b. Symmetric bimodal c. Left skewed

Consider testing the hypotheses Ho: p 0.4 versus Hai p> 0.4. Four possible sample statistics, along with four possible p-values, are given. Match the statistics to their p-values. p= 0.42 p=0.38 p= 0.51 p= 0.46 D

Please help me with this question.

An independent measures study with n = 6 in each sample produces a sample mean difference of 8 points and Sm1-m2= 2. What is the value for the T statistic? A. 1 B. 2 C. 4 D. 4/-8

What is the standard error for the independent sample t statistic for the two samples?             Sample 1 n = 6, SS = 56             Sample 2 n = 4, SS = 40 Select one: 2.24 9.6 12 5

Consider the hypothesis test below. Ho: P1 P2 ≤0 Ha : Pi-P2 > 0 The following results are for independent samples taken from the two populations. Sample 1 731= 100 P₁ = 0.24 Use pooled estimator of p. a. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. 0.0022 b. With a = 0.05, what is your hypothesis testing conclusion? Conclude the difference between the proportions is greater than 0 Sample 2 72 = 300 P₁ = 0.14

For the last part of the question, the options are:   Fail to reject OR reject;   Sufficient OR not sufficient;   is OR is not;   Thanks!

Test the claim below about the mean of the differences for a population of paired data at the level of significance a. Assume the samples are random and dependent, and the populations are normally distributed. Claim: 0 = 0 E. Ho: Hd 0 Ha: Hd s0 The test statistic is t= 1.43 . (Round to two decimal places as needed.) The critical value(s) is(are) to = (Round to two decimal places as needed. Use a comma to separate answers as needed.)
