A 2005 study looked at a random sample of 800 Canadians between the ages of 18 and 24 years, and asked them the following yes or no question: "When nothing is occupying my attention, the first thing I do is reach for my phone.” 77% responded yes to this question. 1) Using the above scenario, construct and interpret a 90% confidence interval.

2) Using the above scenario, test the claim and draw the appropriate conclusion at α = 0.05 that more than 75% of all Canadians in this age group would respond "yes" to the given statement.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
