I need help with this question. Thank you. Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test.Ho: p=0.3 versus H₁ p > 0.3n = 100; x = 40; α = 0.1Click here to view page 1 of the table.

A study compared the achievement scores (on an interval scale from 0 to 20) on an academic test of 10 males and 10 females tested either early in the day or late in the day. The data are in Table 5 below. Do males and females differ in their academic performance depending on whether they write the assessments early or late in the day? Test at an alpha at 0.05 and use all of the steps of hypothesis testing.

A nationwide study of undergraduate students reported that the mean number of drinks consumed per week during the spring semester is 7.96. The mean number of drinks consumed per week at USC is 7.64 (s.d.=2.55, N=412 Health services is concerned that USC students are consuming significantly more alcohol per week than the national average. Using an alpha level of .05, Is there sufficient evidence to be concerned? Be sure to select the correct critical value for the alternative hypothesis, and then use this evidence to make your conclusion
Given the SPSS output (b) State the appropriate null and alternative hypotheses to test whether the medication has been effective in decreasing blood glucose level. (c) Calculate the value of the test statistic and test the hypotheses assuming α = 0.05 using critical value- approach. d) Find the p-value. NOTE: Please note that the hypotheses should be written using notation μD and indicate how you obtain the difference D = Before Medication - After Medication or D = After Medication - Before Medication which my alter your hypotheses. Although SPSS provides p-value (i.e. Sig-(2-tailed) in SPSS output) assuming the test is two-tailed, students need to divide the SPSS p-value by 2 to get the right p-value for our right-tailed test. This problem also needs to be solved using critical value approach. You need to find the critical value from the t-table as critical value is usually not reported in SPSS output and carry out all 4-step process to do the hypothesis test.
A random sample of 460 observations produced a sample proportion equal to 0.36. Find the critical and observed values of z for the following test of hypotheses using α=0.02. H0: p=0.30 versus H1: p>0.30. Round your answers to two decimal places. zcritical =Enter your answer; z_critical
You can lower the likelihood of making a Type I error by: raising the alpha level to 0.10 lowering the alpha level to 0.01 having two statisticians interpret the SPSS output none of these options would help
