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 diagnose 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 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) *** (1ype integers or decimais. Do not rouna.) O A. The 90% confidence interval for mean magnesium level indicates that 90% of hypertensive patients in the sample had a magnesium level between and milligrams per deciliter. B. The 90% confidence interval for mean magnesium level indicates that the true mean magnesium level in hypertensive patients is between 1.84058 and 1.86418 milligrams per deciliter with 9 confidence. OC. The 90% confidence interval for mean magnesium level indicates that the mean magnesium level will be between and milligrams per deciliter in 90% of similarly constructed samples. OD. The 90% confidence interval for mean magnesium level indicates that 90% of all hypertensive patients will have a magnesium level between and milligrams per deciliter. c. If the confidence level is increased to 95%, what will happen to the width of the intervals? Increasing the confidence level 95% will cause the critical value to increase. This means that the width of the confidence interval will increase. d. If the sample of hypertensive patients is increased from 60 to 120, what will likely happen to the width of the intervals? Increasing the sample size from 60 to 120 will change the standard deviation of from approximately to approximately This means that the width of the confidence interval will
