We have to take decision about null hypotheses from given data.

If my p-value = .322 and my significant level is .05 , then My Null Hypothesis is rejected and I must accept the Alternative hypothe I cannot make a decision until I know my sample size. My Alternative hypothesis becomes the new Null Hypothesis My Null Hypothesis is not rejected

You are a research assistant at a zoo. The question of your study is "Has the proportion of baby zebras born in zoos has changed from 10%?". Your supervisor asks that you run a hypothesis test using a significance level of 0.05. From the study, you obtain a z-score of 0.788. What type of z test is appropriate? What is the ? Right, one-tailed test. = +1.645 Right, one-tailed test. = -1.645 Left, one-tailed test. = +1.645 Left, one-tailed test. = -1.645 Two-tailed test. = +1.645 and -1.645
Can't Find Test statistic or p-value :(
the answer for part b was given to me by a tutor 3.79 and the system shows that is incorrect, please help where the red x is.
You are conducting a hypothesis test where the null hypothesis is that mu is less than or equal to 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, rather than mu<= 850, your null hypothesis was that mu >= 850?
4) We are running a hypothesis test to see if weight of African zebras is significantly different than that of Arabian horses. We assume weight in both populations is normally distributed and both populations have the same population variance in weight which is unknown to us, so we use the sample variances to estimate the standard error for our calculations. Our sampling has 8 African zebras and 6 Arabian horses. We find 3.01 as the absolute value of our standardized test statistic for our sample data. Is this data significant at the .02 level of significance? NONE OF THE OTHERS NO YES
What is the null hypothesis? Why do we want to reject our null hypothesis? The first step is the find the mean of our sample and compare it to the "hypothesized" mean of our null hypothesis—why do we do that? We use the results of our first step to calculate a test-statistic. Why is this important and how does it relate to the concept of z-score, which we learned a few weeks ago? What is a p-value? What role does it play in the rejection of the null hypothesis? What does it mean to reject the null hypothesis? Does that guarantee that the null hypothesis is false?
first question is done only need the rest thenks!
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?

These are the summary statistics for independent simple random samples from two populations. x1=23, s1=2, n1=10, x2=29, s2=7, n2=25 Left tailed test, significance level is 0.05 or 95% What is the test statistic, critical value, and conclusion for the hypothesis test?
