In statistical inference, the P-value of a hypothesis test isthe probability, if the null hypothesis was true, that the statistic would take a value atleast as extreme as that actually observed.the probability of the significance level alpha.the probability that the null hypothesis is true.the probability that the alternative hypothesis is false, if the data are a random samplefrom the target population. When interpreting a hypothesis test, report the P-value anddescribe how much evidence it provides against the alternative hypothesisdescribe how much evidence it provides against the null hypothesisstate whether it is smaller than the significance level alphaO state whether it is greater than the significance level alpha

Use the technology display, which results from the head injury measurements from car crash dummies listed below. The measurements are in hic (head injury criterion) units, and they are from the same cars used for the table below. Use a 0.01 significance level to test the given claim. Test the null hypothesis that head injury measurements are not affected by an interaction between the type of car (foreign, domestic) and size of the car (small, medium, large). What do you conclude? Click the icon to view the data table and technology display. What are the null and alternative hypotheses? O A. Ho: Head injury measurements are affected by an interaction between type of car and size of B. Ho: Head injury measurements are not affected by an interaction between type of car and size of the car.

You are conducting a hypothesis test where alternative (research) hypothesis is that mu is greater than 850. You are testing at the 0.01 significance level. You take a sample of size 64 and calculate your test statistic to be -1.50. What would your test statistic be if you were testing, instead, at the 0.10 significance level?
I need the test static, critical value , null & alternative hypothesis , conclusion & also probably p value Thankyou so much I need help kn working these out.
Bruce a store owner would like to determine if a new advertising initiative has increased the proportion of sales he makes to woman is more than 75% to test as he gathers information on 150 random sales and finds out 120 of those sales were to woman the following is a set up for this hypothesis test: Ho: p=0.75 Ha: p>0.75 P-value is 0.079 At the 1% significance level, chose the correct solution A. There is sufficient evidence to conclude that of a portion of sales he makes woman woman is more than 75% B. There is not sufficient evidence to conclude that the portion of sales he makes the woman is more than 75% C. There are sufficient evidence to conclude that the before sheet of sales he makes a woman is more than 50% D. There is not sufficient evidence to conclude that the portion of sales he makes woman is more than 50%
When conducting a significance test in practice, how should you choose the alpha level? a) Always use alpha=0.05 since it's the most appropriate for every situation. b) Always use alpha=0.05 since it's the most commonly used one. c) Use a larger alpha when the consequences of mistakenly rejecting the null hypothesis are more serious. d) Use a smaller alpha when the consequences of mistakenly rejecting the null hypothesis are more serious.
A p-value smaller than the significance level, a means.... We should reject the Null Hypothesis O We should not reject the Null Hypothesis
