What happens to the power of a hypothesis test if the significance level is decreased without changing the sample size? Explain your answer.
True or false, explain: In a goodness-of fit test, if the p-value is 0.0153, in general, do not reject the null hypothesis.
How is ANOVA similar to and different from a t-test?
Hi! Help me with this please. Clean and clear solution. Thank you so much! Hypothesis Tests for Two Samples (Use the 5 Steps).
Hypothesis Test is conjectured that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is 0.62. Of interest is to test this claim versus the alternative that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62. A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (and the other 108 did not). If appropriate, use this information to test if the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62 at the a = .10 level of significance. Which of the following provides both the correct null and the correct alternative hypothesis for this situation? НО: п = 0.62 Ha: π 0.62, Ha::n 0.58 Ha:: π < 0.62
Kruskal-Wallis test is the equivalent of two-way ANOVA. Questions TRUE or FALSE ?
True/false: Some researchers have suggested that blood pressure may tend to be higher on average when measured on a subject's right arm than on their left arm. A doctor decided to investigate this conjecture by taking readings of the systolic blood pressure on both arms of a random selection of twelve patients at his practice. A paired samples t-test can be applied.
When and why would you conduct an ANOVA rather than a t-test?
Explain what is a Hypothesis and how can we apply Hypothesis Testing into the Statistical world, any practical applications?
Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data speeds at airports, the mean is u= 13.00 Mbps. The sample size is n= 25 and the test statistic is t= - 1.144. P-value = (Round to three decimal places as needed.) Enter your answer in the answer box and then click Check Answer.

Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected randomly from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the proportion of all adults in the town that have been exposed to this strain of the flu is 8%
