A survey was done on 28 students, and the distribution of total study hours per week is bell-shaped with a mean of 13 hours and a standard deviation of 3.1 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students spend between 12.41 X hours and 13.58 x hours on Statistics each week. b) 95% of the students spend between 11.82 X hours and 14.7 X hours on Statistics each week. c) 99.7% of the students spend between 11.24 X hours and 14.76 X hours on Statistics each week.
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly more than 0.79. You use a significance level of a 0.01. Ho:p = 0.79 H1:p > 0.79 You obtain a sample of size n 253 in which there are 213 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null
