What sample size is needed to give a margin of error within±0.8 in estimating a population mean with 90% confidence, assuming a previous sample had s = 25. Round your answer up to the nearest integer. sample size = i
A researcher would like to know how much physical endurance is affected by a common herbal supplement. The researcher measures endurance for a sample of n = 9 participants. Each is then given a 30-day supply of the herbs and, one month later, endurance is measured again. For this sample, endurance increased by an average of MD= 6 points with SSD = 216. a. make a point estimate of the mean difference in endurance after taking the herbs. b. make a 95% confidence interval estimate of the population mean difference.

Assume that Christmas trees sold in a farm have heights that are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. Find the value of the quartile Q3 (75% of trees are shorter than this height). 65.3 inches 64.3 inches 66.1 inches O 67.8 inches
Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
