In a study of the relationship between pet ownership and physical activity in older adults, 619 subjects reported that they owned a pet, while 1904 reported that they did not. give a 90% confidence interval for the proportion of older adults in this population who are pet owners. (round your answers to three decimal places.)

(0.230,0.260)

Step-by-step explanation:

The confidence interval for proportion is given by :-

Given : Number of subjects reported that they owned a pet = 619

Number of subjects reported that they did not own a pet =1904

Total subjects =

Significance level :

The proportion that of older adults in this population who are pet owners :-

Now, the 90% confidence interval for the proportion of older adults in this population who are pet owners is given by :-

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
