1. A magazine reported 66% of all dog owners usually greet their dog before greeting their

spouse or children when they return home at the end of the workday. Researchers select 40

dog owners at random and ask them whom they greet first when returning home. The 95%

confidence interval for the proportion of owners who greet their dog first is 0.475 to 0.775.

a) Interpret the confidence interval,

b) Calculate the point estimate and margin of error used to create this confidence interval,

c) Based on the confidence interval, is it plausible that the true proportion of all owners whi

greet their dog first is 66%? Explain.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
