Answer:
Correct option: (a)
Step-by-step explanation:
A confidence interval is an interval estimate of the parameter value.
A (1 - <em>α</em>)% confidence interval implies that the confidence interval has a (1 - <em>α</em>)% probability of consisting the true parameter value.
OR
If 100 such confidence intervals are made then (1 - <em>α</em>) of these intervals would consist the true parameter value.
The 92% confidence interval for the mean annual phone charge of all Vopstra customers is:
This confidence interval implies that true mean annual phone charge of all Vopstra customers is contained in the interval ($405, $535) with 0.92 probability.
Thus, the correct option is (a).

Answer: Hello mate!
each school graduate has a 68% to find a job in their chosen field within a year after graduation.
And we want to know the probability for a randomly chosen group of 11 graduates to all get a job in their area within a year of graduating.
(you used the numbers 6868% and 1111, I am assuming that you write this wrong and repeated the numbers)
Ok! so each of the 11 students has the same probability of 0.68 to find the job. Then the joint probability for the 11 events ( where the events is that each one finds a job) is the product of the probability for each one.
P = (0.68)^11 = 0.01437
and if we round it to the nearest thousandth we get:
p = 0.014
