According to a recent​ report, 46​% of college student internships are unpaid. A recent survey of 120 college interns at a local university found that 64 had unpaid internships. A. Use the​ five-step p-value approach to hypothesis testing and a 0.05 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.46. b. Assume that the study found that 70 of the 120 college interns had unpaid internships and repeat​ (a). Are the conclusions the same?   Let π be the population proportion. Determine the null​ hypothesis, H0​, and the alternative​ hypothesis, H1.   H0: H1:   T-Stat=___ p-value=____   Whats the final conclusion?   __A__ the null hypothesis. There __B__ sufficient evidence that the proportion of college interns that had unpaid internships is __C__ 0.46 because the p-value is __D__ the level of significance.    A: Reject or do not reject B: is not or is  C: Different from, greater than or less than D: greater than or less than

A nonprofit company concerned with the school dropout rates has designed a tutoring program aimed at students between 16 to 18 years old. A national center for educational statistics reported that the high school dropout rate for the year 2000 was 10.9​%.One school​ district, who adopted the use of the​ nonprofit's tutoring program and whose dropout rate has always been very close to the national​ average, reported in 2004 that 158 of their 1769 students dropped out. Is their experience evidence that the tutoring program has been​ effective?   Determine the hypotheses for this test. Choose the correct answer below A. H0​: p=0.109 HA​: p≠0.109   B. H0​: p≠0.109 HA​: p=0.109   C. H0​: p=0.109 HA​: p<0.109   D. H0​: p=0.109 HA​: p≥0.109   E. H0​: p≥0.109 HA​: p=0.109   F. H0​: p≤0.109 HA​: p=0.109   Compute the test statistic. enter your response here ​*______*   Find the​ P-value. enter your response here* ______* 3. Is their experience evidence that the tutoring…

It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handed desks to place in the big lecture halls being constructed on its campus. In a random sample of 120 students of its 12124 students, 15 were left-handed. Does this provide enough evidence to show that students at this college have a higher percentage of left-handers than the general American population? Use a 10% level of significance.

Portland State University (PSU) reported that 64% of their students receive financial aid. A PSU administrator feels that their school may have a different proportion compared to all of Oregon schools. A random sample of 409 students in Oregon found that 259 receive financial aid. Test the claim that proportion of students that receive financial aid in Oregon is different than PSU. Use a 1% significance level. Give answer to at least 4 decimal places. a. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: Select an answer ?v H₁: Select an answer ? ✓ Based on the hypotheses, compute the following: b. Test Statistic = c. p-value = d. Based on the above we choose to Select an answer e. The correct summary would be: Select an answer that the proportion of students that receive financial aid in Oregon is different than the PSU reported value of 64%.
