To find 3% of $2 you would first see what 10% is. therefore the mutiplier here would be .3
Using a t-distribution calculator, it is found that the critical value of the test statistic t is
.
<h3>How to find the critical value of a t-test?</h3>
- The critical value is found using a calculator.
The inputs are:
- The amount of degrees of freedom, which is one less than the sample size.
In this problem, we have a<u> lower(left-tailed) test, with 10 - 1 = 9 df and a level of significance of 0.1</u>, hence the critical value is
.
