Question
Are most student government leaders extroverts? According to Myers-Briggs estimates, about 82% of college student government leaders are extroverts.+ Suppose that a Myers-Briggs personality preference test was given to a random sample of 75 student government leaders attending large national leadership conference and that 54 were found to be extroverts. Does this indicate that the population proportion of extroverts among college student government leaders is different (either way) from 82% ? Use a = 0.01. USE SALT (a) What is the level of significance? 0.01 State the null and alternate hypotheses. O Ho: P 0.82; H₁: p = 0.82 O Ho: p > 0.82; H₁: p = 0.82 O Ho: P = 0.82; H₁: p > 0.82 O Ho: P = 0.82; H₁: p < 0.82 O Ho: P = 0.82; H₁: p = 0.82 (b) What sampling distribution will you use? O The Student's t, since np < 5 and nq < 5. O The Student's t, since np > 5 and nq > 5. O The standard normal, since np < 5 and nq < 5. The standard normal, since np > 5 and ng > 5. ..... What is the value of the sample test statistic? (Round your answer to two decimal places.) (c) Find the P-value of the test statistic. (Round your answer to four decimal places.) Sketch the sampling distribution and show the area corresponding to the P-value.

Are the data statistically significant at level a? O At the a = 0.01 level, we reject the null hypothesis and conclude the data are statistically significant. O At the α = 0.01 level, we reject the null hypothesis and conclude the data are not statistically significant. O At the α = 0.01 level, we fail to reject the null hypothesis and conclude the data are statistically significant. O At the α = 0.01 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. (e) Interpret your conclusion in the context of the application. O There is sufficient evidence at the 0.01 level to conclude that the true proportion of extroverts among college student government leaders differs from 82%. O There is insufficient evidence at the 0.01 level to conclude that the true proportion of extroverts among college student government leaders differs from 82%.
