Suppose you have constructed a 90% confidence interval of a population mean, (19.7, 21.2). decide which statement below is the correct interpretation of the results. justify your choice, with as much detail as possible, and in your own words. with 90% confidence, the mean is in the interval (19.7,21.2). there is a 90% probability that the actual mean will be in the interval (19.7,21.2).

the answer is true.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

x=0
