Answer:

0.007 hour or 25.2 seconds

Step-by-step explanation:

From the question, we are told that for Scott Dixon,he completed

500 laps in approximately = 3.5 hours. 1 lap approximately =

Cross Multiply

= 1 lap × 3.5 hours = 500 laps × a hours

a hours = 1 lap × 3.5 hours/500 laps

a hours = 0.007hours

We can convert 0.007 hours to seconds

60 seconds = 1 minute

60 minutes = 1 hour

1 hour = 60 × 60

= 3600 seconds

1 hour = 3600 seconds

0.007 hour =

0.007 hour × 3600 seconds

= 25.2 seconds

Therefore, it took Dixon approximately 0.007 hour or 25.2 seconds did it take for him to complete 1 lap

Zepler [3.9K]

<u>Answer</u>: No, we do not have sufficient evidence to conclude that the mean call duration, µ, is different from the 2010 mean of 9.4 minutes.

Step-by-step explanation:

As per given , we have

H_0: \mu=9.4\\\\H_a:\mu\neq9.4, since H_0 is two-tailed so , the test is a two tail test.

Since population standard deviation is unknown, so we use t-test.

Critical value (two-tailed) for significance level of 0.01= t_{n-1,\alpha/2}=t_{49, 0.005}\pm2.609228

For n =50 , \overline{x}=8.6 and s= 4.8

Test statistic : t=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

t=\dfrac{8.6-9.4}{\dfrac{4.8}{\sqrt{50}}}\approx-1.18

Since test statistic value (-1.18) lies in critical interval (-2.609228, 2.609228), it means the null hypothesis is failed to reject.

We do not have sufficient evidence to conclude that the mean call duration, µ, is different from the 2010 mean of 9.4 minutes.
