Read instructions for entering answers carefully.  Previous studies have indicated that approx. 40% of college students work full time.  Joanna thinks that this is higher amongst college students at 2 year community colleges. She took an SRS of 140 college students from the local community college and found that 65 worked full time. Is this sufficient evidence (at the 5% significance level) to support the claim that more than 40% of community college students work full time?   Q1: Fill in the hypothesis.  Null Hypothesis: H0: p =[forty] Alternate hypothesis: Ha: p =[forty2]   Q2:Assuming the null hypothesis is true, the sampling distribution for sample proportions is N([forty3],[sd]) Write both as decimals. Round the standard deviation to 4 decimal places.   Q3: Find the rejection region: Round to 2 decimal places The rejection region on the standard normal curve is ([ll],

Joanna wants to estimate the proportion of college students at two year community colleges who work full time. From an SRS of 140 students from local community colleges you find that 65 work full time. Create a 95% confidence interval. Enter the lower value of the interval (rounded to two decimal places)
