dentify test statistic Identify P value Identify a conclusion Fail to reject H0... Reject H0....

Solve the last question please

Hypothesis Testing Using a P-Value  identify the claim and state Ho and Ha. find the standardized test statistic z. find the corresponding P-value. decide whether to reject or fail to reject the null hypothesis. interpret the decision in the context of the original claim.

thanks

Identify a question you would like to answer using statistics which may be answered using a confidence interval in plain English.   Example:  What is the average GPA of an incoming student at MC   Identify the parameter related to your question and its symbol and its name.   Example:  m, mean   identify the statistic related to your question and its symbol   Example: x(bar), sample mean   List  your data(try to get at least 10 in your sample).   Example:  3.28, 2.41, 3.64, 1.28,3.56, 2.57, 3.10,2.94, 2.45, 3.16, 2.45   Describe your population of inteeest.   Example: All students at MC   Describe your sample.   Example:  11 Studens in my statistics class   Comment on how you obtained your sample   Example: Conducted an email survey of the students in my statistics class   Comment on the bias in your sample   Example;  This sample is biased since it is only people in math 117, who need certain perquisites to take the course, this underrepresents students without the…

Chose the correct answer

Claim: Fewer than 92% of adults have a cell phone. In a reputable poll of 1178 adults, 87% said that they have a cell phone. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)

In want test the claim that the mean number of children that students have is less than 3. The collected data from a sample of students on how many kids each student has is below. Use as significance level of a=.10. (If you need to use ,≤, or use the little symbol above and then choose relationships) 1,3,2,0,0,4,2,1,0,0,0,1,2,0,0,1,4,2,1,0,0,0,0,3 Claim: ,=, ≤, ≥, and then a number) 3 (Two decimals like -4.97) (reject/fail to reject) Ho (One of these , , , and then a number) (This should be O because it says , , ≤, 2, and then a number) (supports/fails to support/rejects/fails to reject) the claim that the mean is less than 3.

Reliability of a measure may be established byGroup of answer choices A.  giving the test to the same people on two different occasions and correlating the two sets of scores B.  correlating scores from alternate forms of the same test C.  correlating the test with some independent criterion D.  a, b, and c E.  a and b only

STAT&PROB11-Finals The Language of Hypothesis Testing Suppose we wish to test H, : µ47. What will be the result if we conclude that the mean is greater than 47 when its true value is really 52? O We have made a Type I error. O We have made a Type II error. O We have made a correct decision. O None of the above is correct. 30 31 32 33 34 35 36 37 38 Nex 29
