Suppose x has a distribution with = 12 and a = 11.LAUSE SALT(a) If a random sample of size n = 36 is drawn, find , and P(12 ≤ x ≤ 14). (Round a to two decimal places and the probability to four decimal places.)Hx=ox=P(12 ≤ x ≤ 14) =(b) If a random sample of size n = 57 is drawn, find , and P(12 ≤ x ≤ 14). (Round a to two decimal places and the probability to four decimal places.)Hx0x =P(12 ≤ x ≤ 14) =(c) Why should you expect the probability of part (b) to be higher than that of part (a)? (Hint: Consider the standard deviations in parts (a) and (b).)The standard deviation of part (b) is -Select- part (a) because of the --Select-- sample size. Therefore, the distribution about is --Select--

Suppose that you have a four-sided die that is equally weighted (i.e. equal chance of any of the four sides landing face up). The four values on the die are [12.5968, 2, -2 and -12.5968] . If we roll the die 81 times, record the average, and repeat this process a total of 100 times, what does the central limit theorem predict will be the standard deviation of the set of averages? A. 1.00 B. 0.729 C. 0 D. 1.40
Suppose the mean grade for a statistic midterm was 75 with Standard Deviation of 10. Assume that the grades are normally distributed. a) What percentage of students received a grade less than 70? b) If 2 students failed the exam i.e. their grades were less than 60, how many students took the test? ( Hint: Focus on x< 60 first)
An elevator has a play card stating that the maximum capacity is 1980 pounds 12 passengers so 12 adult male passages can have a mean way of up to 1180÷12 = 165 pounds. If the elevator is loaded with 12 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 165 lb. Assume that weights of males are normally distributed with a mean of 172 pounds and a standard deviation of 27 pounds. Does this elevator appear to be safe?
Suppose that the speed at which cars go on the freeway is normally distributed with mean 76 mph and standard deviation 5 miles per hour. Let X be the speed for a randomly selected car.a.

If one of the cars is randomly chosen, find the probability that it is traveling between 79 and 85 mph. Round to 4 decimal places.
