The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
Step-by-step explanation:
A newsletter publisher believes that 60`% of their readers own a Rolls Royce.
This means that the null hypothesis is: 
That is, that the proportion of their readers who own a Rolls Royce is of 0.6.
A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim.
The alternate hypothesis is: 
After performing a test at the 0.020.02 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher's claim?
The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
Answer:
1.) 15.24 J
2.) 7.62 W
Step-by-step explanation:
Given that You do a pull-up, lifting yourself by 0.5 in 2 seconds. If your weight is 600 N,
Convert inches into metres
1 inches = 0.0254 metres
Work done = Force × distance
Work done = 600 × 0.0254
Work done = 15.24 J
Power is the rate at which work is done.
That is,
P = WD / time
Power = 15.24 / 2
Power = 7.62 W
Therefore, 15.24 Joule of work done must be done and 7.62 watt of power output must be required to lift the yourself.
