Answer:
Follows are the solution to the given question:
Step-by-step explanation:
In point a:
The confidence interval will not provide convincing proof that only the two population prolongations differentiate because a 99 percent confidence interval for both the difference throughout the true promotion around -0.020 and 0.120 is included 0.
In point b:
This confidence interval gives strong evidence also that two population proportions were identical because there is a confusion interval of 99 percent between -0.020 and 0.120 for the difference in the true percentage of the population that say "Yes".
A composite has more than 2 ways to divide itself
57.29 you do 48.55 times .18 which =8.74 then add the tip with the initial cost 8.74+48.55 =57.29 to get your answer 57.29
First you need to make a multiplier:
1-(12/100) = 0.78
Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16
This means it cost $17.16 after the 12% sales tax.
Hope this helps! :)
