An important part of the customer-service responsibilities of a telephone company relate to the speed with which troubles in residential service can be repaired. Suppose that past data indicate that the likelihood is 0.70 that troubles in residential service can be repaired on the same day. If a sample of 100 troubles is selected, what is the probability that the proportion repaired on the same day is

(a) between 0.70 and 0.75?
(b) at least 0.70?
(c) between 0.60 and 0.80?
(d) What would be your answers to (a)-(c) if n = 50?

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
