The easist way i can think of doing this would be to multipy the 22.5 miles by three so you can see how far he would go if he had one hour to travel at that average speed, the answer after multipying by 3 is 67.5 miles per hour, which in most plavces he would b considered speeding.
Answer: There is sufficient evidence to support the claim that the bags are under-filled.
Step-by-step explanation:
Since we have given that
Sample mean = 411
Standard deviation = 20
n = 9
So, the test statistic value is given by
At 0.025 level of significance,
critical value z = -2.306
since -2.306<-1.05
so, we will reject the null hypothesis.
Yes, there is sufficient evidence to support the claim that the bags are underfilled.
The area of the circle is expressed in the formula A = pi r^2 while the formula of getting the circumference of the circle is C = 2pi *r. Trying to express A in terms of C, we square C first into C2 = 4pi^2r^2. In this case, the answer to this problem therefore is A = C^2/4 pi. Answer is B
