Sample information: 24 out of 1000 people who were surveyed had type 2 diabetes. Use the above sample information and construct

notka56 [123]

Solution :

The sample proportion $(\hat p)=\frac{24}{1000}$

= 0.024

<u>90% confidence interval </u>

The standard deviation = $\sqrt{\frac{\hat p(1-\hat p)}{n}$

= $\sqrt{\frac{0.024(1-0.024)}{1000}$

= 0.00484

z = 1.645 for 90% CI

Upper band = 0.024 + (0.00484 x 1.645 ) = 0.03196

Lower band = 0.024 - (0.00484 x 1.645 ) = 0.01603

Therefore, the 90% CI is (0.016, 0.032)

<u />

<u>99% confidence interval </u>

z = 2.576 for 99% CI

Upper band = 0.024 + (2.576 x 0.00484 ) = 0.0365

Lower band = 0.024 - (2.576 x 0.00484 ) = -0.0115

Therefore, the 99% CI is (0.0115, 0.0365)

Alexandra [31]

<h2>Total distance Mr. Webester drives per week to his office is 182 miles.</h2>

Step-by-step explanation:

Number of days per week he goes to office = 4

The distance to Mr. Webesters office from home = 23.7 miles.

The distance to Mr. Webesters home from office = 21.8 miles.

Total distance drove per day = The distance to Mr. Webesters office from home + The distance to Mr. Webesters home from office

Total distance drove per day = 23.7 + 21.8 = 45.5 miles

Total distance Mr. Webester drives per week to his office = Number of days per week he goes to office x Total distance drove per day

Total distance Mr. Webester drives per week to his office = 4 x 45.5

Total distance Mr. Webester drives per week to his office = 182 miles

Total distance Mr. Webester drives per week to his office is 182 miles.
