Prompt The cell-phone datafile is available in the Data section below. Once again, here is the research question for this lab. Based on a recent study, roughly 80% of college students in the U. S. own a smartphone. Is the proportion of smartphone owners lower at this university? Respond to each of the following in your initial post. State your hypotheses in symbolic form and in words. (The following should be clear in your the population of interest and the meaning of the proportion p in terms of the variable Cell.) StatCrunch uses a normal model to estimate the P-value probability. Verify that normality conditions are met. Use StatCrunch to conduct the hypothesis test. (directions) Copy and paste the results (the StatCrunch output window) into your initial post. Give your P-value and interpret its meaning as a conditional probability. State a conclusion that answers the research question. Use a significance level of 5%. (Your answer should include the P-value and reference the population and the variable Cell.)
