The security department of a factory wants to know whether or not the true average time required by the night watchman to walk hisround is 25 minutes. If in a random sample of 42 rounds, the night watchman averaged 25.6 minutes with a standard deviation of 1.5minutes, determine at the 0.01 level of significance whether this is sufficient evidence to reject the null hypothesis.Answer the following questions according to the text above.1- Choose the relevant hypotheses.Ho:H:2- Compute the test statistic.(Note that; za means z, or ta(df)3- What is the decision rule for the test.means t,(df) )4- State your decision and conclusion.5- Calculate the p-value for the test.

As per our guidelines, we are allowed to answer first three sub-parts only. Thanks The following…

Hypothesis Test of the Difference Between Two PAIRED Means. Im pretty sure this should be a one tailed test, as does my teacher does an example for this and her's had one tail. Help me understand which tail it is (what lead you to believe it was right or left tail.) I will need the test statistic and critical value(s). You will need the null and alternative (H0: u1=u2, H1: u1=/=u2). The equation that is needed to solve this is t= d *bar* - Ud / (Sd/*square root* of n) D.O.F formula to be used is n-1. This is all the infomartion I think you need might need to determine the kind of problem this is. I've asked this question before but it seems I didn't provide enough information and the answers included two tailed test or something else. Oh also I need these formulas to be used, as in no excel to speed things up because as much as i like shortcuts I need to understand this concept. Standard dev or Sx should be 1.414213562. Pretty sure this is right, not 100%. d *bar* should = -2, pretty…

(b) x = 25.1 Find the value of the test statistic. Find the p-value. p-value - State your concluslon. O Reject Ho. There is sufficient evidence to conclude that u z 22. Reject Hg. There is insufficient evidence to conclude that u = 22. O Do not reject Ho. There is insufficient evidence to conclude that u + 22. O Do not reject Ho: There is sufficient evidence to conclude that u + 22. (c) x = 21 Find the value of the test statistlc. Find the p-value. p-value = State your conclusion. O Reject Ho. There Is sufficlent evidence to conclude that u + 22. O Reject Hg. There is insufficient evidence to conclude that u + 22. O Do not reject Ho- There is insufficient evidence to conclude that pu + 22. O Do not reject Hp. There is sufficient evidence to conclude that u + 22.
Can you please help me located the null?
Please find (c), (d), (e) and if possible check to see if my degrees of freedom is correct please:)
It's just one question with sub-parts. Since you are only allowed to do 3 questions please do D, E, F the last 3 only. Thank you
uppose you reject the null hypothesis H0: μ = 101. It turns out the population mean is actually equal to 101. You have made a Group of answer choices Type I and Type II errors the correct decision Type II error Type I error
H0: p1=p2 H1: p1<p2 1) Identify the test statistic. 2)Identify the P-value.
