Question

Using traditional methods, it takes 10.8 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 11 students and observed that they had a mean of 11.2 hours with a standard deviation of 1.7. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal. Find the value of the test statistic.

Answer 1

Answer:

Hence the value of the test statistic is 0.780.

Step-by-step explanation:

Given:

Test Statistic:-

$t=\frac{\bar{X}-\mu }{\frac{S}{\sqrt{n}}}$

$t=\frac{11.2-10.8 }{\frac{1.7}{\sqrt{11}}}$

$t=\frac{0.4}{0.5126}\\t=0.780$
