Using the t-distribution, it is found that the proportion in a t-distribution less than −1.4 if the samples have sizes n1=30 and n2=40 is of 0.083.
<h3>How to find a proportion in a t-distribution?</h3>
The proportion is found using a calculator, with three inputs:
- The tail of the test, if it is left, right, or two-tailed.
- The amount of degrees of freedom.
In this problem, we have a left-tailed proportion, as we want the proportion that is less than a value, with test statistic t = -1.4 and 30 + 40 - 2 = 68 df, hence the proportion is of 0.083.

Answer:
24/25 walls per gallon
Step-by-step explanation:
to get per gallon, we want gallon to be zero.
5/8 gallon of paint: 3/5 of wall
multiply by 8/5 on both sides
1 gallon: 24/25 of wall
24/25 walls per gallon.
