Using traditional methods, it takes 108 hours to receive a basic driving license. a new license training method using computer aided instruction (cai) has been proposed. a researcher used the technique with 110 students and observed that they had a mean of 107 hours. assume the standard deviation is known to be 7. a level of significance of 0.02 will be used to determine if the technique performs differently than the traditional method. find the value of the test statistic. round your answer to 2 decimal places.

answer: ok

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
