Construct the indicated confidence interval for the population mean u using the t-distribution. Assume the population is normally distributed, c=0.95, x=13.9, s=4.0, n=8.
Which interval is which? Matilda constructed three confidence intervals, all from the same random sample. The confidence levels are 95%, 98%, and 99.9%. The confidence intervals are I. 5.2 <µ<6.8 II. 5.5<µ<6.5 III. 5.4 <µ<6.6 Unfortunately, Matilda has forgotten which confidence interval has which level. Match each confidence interval with its level. 5.2 <µ<6.8 is the (Choose one) confidence interval. 95% 5.5
People with high blood pressure suffer from hypertension. Data on fasting blood sugar (milligrams/deciliter) and magnesium (milligrams/deciliter) in blood specimens collected from 60 patients diagnosed with hypertension were collected. The accompanying technology printout gives 90% confidence intervals for the mean fasting blood sugar (FBS) and mean magnesium level (MAG). Use this information to complete parts a through d below. Variable FBS MAG N 60 60 Mean 102.11 1.85238 StDev 38.91 0.05472 90% CI SE Mean 5.02 ( 93.72, 110.50 ) 0.00706 (1.84058, 1.86418) a.
