The blood pressure (average Of systolic and diastolic measurements) Of each of 38 randomly selected persons was measured. The average was 94.5 mm Hg amd the standard deviation 8.0497 mm Hg Which of the statistical procedures below would you use to estimate the populations mean blood pressure? Confidence interval for paired data One-way analysis Of variance (ANOVA) Confidence for a Single sample Confidence interval for comparing independent samples The most important condition for making reasonable conclusions using statistical inference from sample data is usually. O a. That no calculation are made during confidence interval calculation or hypothesis test procedure. O That the sample size is at leastn:ICO. O c. That the population distribution is exactly normal. O d. That the data can be thought of as a random sample from the of interest. Does reading on a tablet or cellphone at bedtime increase how long it takes to fall asleep? A sample of 12 healthy adults slept in a lab on tvo different nights. In random order, participants read from a print for 30 minutes bef01e going to Sleep or on a tablet for 30 minutes before to Sleep. Scalp electrodes were used to measure how long (in minutes) it took participants reach deep sleep with the tablet than the print book (p-vaIue=0009). Which is the best null hypothesis? O O O a. b. The time it takes to fall asleep after reading on a tablet is different than the time it takes to fan asleep after reading on a print book. The time it takes to fall asleep after reading on a tablet the same as the time it takes to fall asleep after reading on a print The time it takes to fall asleep after reading on a tablet is less than the time it takes to fall after on a print book. The time it takes to fall asleep after tablet time it fall asleep after a
