Answer:
The null and alternative hypothesis are:

There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
Step-by-step explanation:
Consider the provided information.
The claim that the mean tornado length is greater than 2.6 miles.
If there is no statistical significance in the test then it is know as the null which is denoted by
, otherwise it is known as alternative hypothesis which denoted by
.
Therefore, the required null and alternative hypothesis are:

significance level α =0.05
From the given table the test statistic T=2.230166
P-value is 0.0131
0.0131<0.05
P value is less than the significance level, so reject the null hypothesis.
There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
i got:
n = -1 + 3/x
x = 3/n + 1
not sure if this helps but i hope it does somehow

Answer:
The correct answer is,
the area of given triangle = 1875 square feet
Step-by-step explanation:
Formula:
Area of triangle = bh/2
b - Base and h - height
It is given that,a triangle with a base of 50 feet and a height of 75 feet’
<u>To find the area of triangle</u>
base b = 50 feet and height h = 75 feet
Area = bh/2 = (50 x 75 )/2
Area = 3750/2 = 1875 square feet
Therefore the area of given triangle = 1875 square feet
