Step-by-step explanation:
Definition:
Null hypothesis is a statement about the population parameter according to the objective raised by the researcher . It contains '=' , '≤' and '≥' signs.
Alternative hypothesis is also a statement about the population parameter but against null hypothesis . It contains '≠' , '<' and '>' signs.
Let be the average customer waiting time for the population.
Given : The average customer waiting time at a fast food restaurant has been 7.5 minutes.
Objective of test : After using new system , the average customer waiting time is at least 7.5 or less than 7.5.
Then, the null and alternative hypothesis for this scenario will be :
Find the area of each area. Or you can multiply 10 by 18 to get 180. That’s the 4 boxes in the middle. 3 x 6=18. This is the box on the top. The box on the bottom is the same so multiply 18 by 2 to get 36. 36+180=216cm2.
360 degrees is the whole circumference.
300 degrees is 300/360 of the circumference.
The circumference: pi*r*2 = 4*pi = approximately 12.566.
300/360*12.566=10.472 = answer
