The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region, we have to reject the null hypothesis or claim incorrect.

Data;

  • mean = 5.82
  • s = 4.93
  • n = 600
<h3>Test-Static t </h3>

Let's calculate the t-value

t = \frac{x - \mu}{\frac{s}{\sqrt{n} } }

Substitute the values into the equation and solve;

t = \frac{x - \mu}{\frac{s}{\sqrt{n} } } \\t = \frac{5.82 - 5}{\frac{4.93}{\sqrt{600} }} \\t = \frac{0.82}{0.201} \\t = 4.079

The t-value is 4.079.

The allowed significance value = 0.01

The degree of freedom is n -1, which becomes 600 - 1 = 599.

The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region, we have to reject the null hypothesis or claim incorrect.

The amount of deposit, d made in time in other to avoid penalty fee?

Minimum amount that most have been deposited, d :

A truck driver drove 300 miles in 6 3/4 hours. How many miles per hour did the driver drive?
Andru [333]
44.4 miles per hour. You just divide 300 and 6.75 (Think as the 3/4 as quarters each 1 is .25)  then you will get 44.4. To check your answer you would multiply 44.4 and 6.75 and get 299.7. This is not 300 but when you round that .7 to the nearest 10 you will get 300. Hope this helped.<span />
