Betty, an employee of Shining Sun Daycare Centerread an article in Healthy Child Magazine sayingthat the average 3-year-old child is 37 in. tall.Betty works with 10 3-year-olds at Shining Sun,so later that week, she measured the height ofeach child who had just turned or was about toturn 3 years old. Here are the descriptive statisticsfor the sample: M = 35, s = 3.1. State the nondirectional hypothesis.2. Determine the critical t for a = .05.3. Calculate t. Show your calculations.4. Is the height of 3-year-olds in Shining SunDaycare Center significantly different fromthe height given in the magazine?

Find the population mean or sample mean as indicated. Population: 6, 9, 3, 12, 14, 16 O A. x=11 OB. x= 12 O C. µ= 13 ΟD. μ= 10

Determine u, and o; from the given parameters of the population and sample size. u = 84, o = 8, n = 64
