First proportion
Given that a report on the nightly news broadcast stated that 20 out of 208 households without pet dogs were burglarized
Second proportion
where
P = 0.09486
Q = 1 - P = 1 - 0.09486 = 0.90514
<u><em>Step(ii):-</em></u>
Test statistic
Z = -0.1040
|Z| = |-0.1040|
|Z| = 0.1040
Critical value Z = 1.96 at 0.05 level of significance
Answer:
<em>The total price David paid for the computer is $933.12</em>
<em />
Step-by-step explanation:
The cost of the computer will be $1,080 with 20% off and 8% sales tax.
20% of 1080 is 1080(0.20)=216 this means 216 is 20% of 1080, so with the discount the price will be 1080-216=$864
Now we have to find 8% of 864.
864(0.08)=$69.12
So the total price will be 864+69.12= $933.12
The answer will be 5. hope this helped
