g. The company boasts that at least 70% of its salesmen have college degrees. Provide the formal null and alternative hypotheses for a test of this question. Is this a one or two-tailed hypothesis? h. Do you have a large enough sample to conduct the correct hypothesis test? Explain with a calculation why or why not. (Hint: you need to use a specific rule taken directly from our course slides that fits this scenario's sampling distribution) i. If your answer to part "h" is yes, then conduct this hypothesis test based on the 95% confidence level. Do you reject or fail to reject your null hypothesis? Why?
