A university claims that their employment rate directly after graduation is 40%. In a sample of 700 graduates, 224 found to have gained employment directly after graduation. Test the claim that the university's employment rate after graduation is smaller than 40% at the 0.10 significance level. The null and alternative hypothesis would be: H0: ? = 0.4 H0: ? ? 0.4 H0: p = 0.4 H0: p ? 0.4 H0: p ? 0.4 H0: ? ? 0.4 H1: ? ? 0.4 H1: ? < 0.4 H1: p ? 0.4 H1: p > 0.4 H1: p < 0.4 H1: ? > 0.4 The test is: right-tailed left-tailed two-tailed The test statistic is: (to 2 decimals) The p-value is: (to 4 decimals) Based on this we: Fail to reject the null hypothesis Reject the null hypothesis

A research states that 28% of college degrees are from engineering courses. A researcher doesn't believe that this is correct. A sample of 1,000 graduates was used, and it was found out that 295 have finished engineering courses. Test the claim if it has increased at a 0.10 level. What is the correct null hypothesis? Ho: p = 0.28 Ha: p > 0.28 b. Level of Significance: α = 0.10 Computed Test Statistic: zcom = ____ d. Critical Value: 1.282 DECISION: Since the computed test statistic zcom = ____ does not fall the rejection region, ________ the null hypothesis (Ho). CONCLUSION: Therefore, we conclude that at 0.10 level of significance,

A school reports that 76% of its graduates get jobs within one year. You take a random sample of 56 graduates, of whom 40 got a job within one year. Is this enough evidence to show that a significantly smaller percent of graduates get jobs than advertised by the school? (Use α = 0.10) For this study, we should use 1-PropZTest. The null and alternative hypotheses would be: H0: p >= (please enter a decimal) H1: p < (Please enter a decimal) The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤ α Based on this, we should reject the null hypothesis. As such, the final conclusion is that: The sample data suggest that the population proportion is significantly smaller than 76% at α = 0.10, so there is sufficient evidence to conclude that the percent of graduates get jobs within one year is smaller than 76%. The sample data suggest that the population proportion is not significantly smaller than 76% at α = 0.10, so there is not sufficient evidence to conclude that the percent of graduates get jobs within one year is smaller than 76%.

An education researcher claims that 60% of college students work year-round. In a random sample of 200 college students, 120 say they work year-round. At α = 0.10, is there evidence to reject the researcher's claim? Complete parts (a) through (e) below: (a) The rejection region is z < -1.645. (b) The rejection region is z < -1.645. (c) Find the standardized test statistic Z. z = 0.00 (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. (e) Interpret the decision in the context of the original claim: The null hypothesis is rejected. There is not enough evidence to support the researcher's claim.
