- Assume Z is a random variable with a standard normal distribution and c is a positive number. If P(Z>c)=0.1 then P(−c<Z<c)=0.8. True or FalseAssume that the random variable X is normally distributed when mean u= 80 and the standard deviation o=15 compute the probability P( X >92) A. 0.2420 B. 0.1977 C. 0.7881 D. 0.2119Let x be a random variable that represents the level of glucose in the blood (milligrams per deciliter of blood) after a 12 hour fast. Assume that for people under 50 years old, x has a distribution that is approximately normal, with mean ? = 51 and estimated standard deviation ? = 16. A result x < 40 is an indication of severe excess insulin, and medication is usually prescribed. b. What is the probability that x < 40?c. Repeat part (b) for n = 3 tests taken a week apart. d. Repeat part (b) for n = 5 tests taken a week apart.
