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:
150 m and 50 m
Step-by-step explanation:
l= 125 m
w= 75 m
P= 2(125+75)= 400 m
A= 125*75= 9375 m²
l1= 125+25= 150 m
w1= 75-25= 50 m
A1= 150*50= 7500 m² smaller area with same perimeter

Answer:
0 and 2
Step-by-step explanation:
Let the two consecutive integers be 2x and 2x+2
We are given that twice the larger integer is four more than half of the smaller integer
So, Two consecutive integers are 2(0)=0 and 2(0)+2=2
Hence the two consecutive integers are 0 and 2
