GenaCL600 [577]

Answer:

95% Confidence interval: (0.8449,0.9951)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Number of times the dog is right, x = 46

$\hat{p} = \dfrac{x}{n} = \dfrac{46}{50} = 0.92$

95% Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting the values, we get:

$0.92 \pm 1.96(\sqrt{\dfrac{0.92(1-0.92)}{50}})\\\\ = 0.92\pm 0.0751\\\\=(0.8449,0.9951)$

(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.

Scott and Nikki each have a full 1.5-gallon container of liquid laundry detergent. The lid on Scott’s container can hold 3 fluid

Katena32 [7]

There are 128 ounces in 1 gallon
1,5gallons= 192 ounces
Scott = 3 oz per lid
192 divided by 3 = 64 lids of detergent
Nikki = 4oz per lid
192 divided by 4 = 48 1/2 lids
64 - 48.5 = 15.5 lids more

1 meter = 1000 millimeters

so, 5 meters = 5*1000 = 5000 millimeters

and 6000 millimeters = 6000 / 1000 = 6 meters
