Answer:
We cannot infer at the 10% significance level that the assumption of ski centers is wrong
Step-by-step explanation:
The null hypothesis for this question can be stated as
Null hypothesis H0: =4
Alternate hypothesis Ha:
The test is two tailed
Standard Deviation –
= 2
z=(4.84-4)/(2/sqrt(63))
=3.33
Z(0.1/2)=1.645 is less than Z =3.334
Hence, we will reject H0
Hence, the average growth skier ski’s four times a year is not true

Answer:
Robot will take 
hour to complete each task.
The robot can complete 
tasks in one hour.
Step-by-step explanation:
We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.
To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:
Now we will convert division problem into multiplication problem by flipping the 2nd fraction.
Therefore, robot will take hour to complete each task.
To find tasks completed by robot in one hour we will use proportions.
Therefore, the robot can complete tasks in one hour.
Answer:
The answer is 3 3/4
Step-by-step explanation:
First, you have to find a common denominator. 4 and 6 both can first into 12, so 12 is the common denominator. Then you subtract.
