If a number has only one, prime, factor, then that number MUST be a perfect square, cube, etc. 11^3=1331, which is a four digit palindromic number that has exactly one prime factor. Hope this helps!
The answer is 4√7.
Area (A) of a square can be expressed as the square of its side (a):
A = a²
It is given:
A = 112 ft² = a²
⇒ a² = 112 ft²
⇒ a = √112 = √(16*7) = √16 * √7 = √(4²) * √7 = 4 * √7 = 4√7
In hypothesis testing, A null hypothesis (H0) is a claim which the person conducting the research wants to test while an alternative hypothesis (H1) is a contradiction of the null hypothesis.
There are two types of tests in hypothesis testing.
One tailed test: In one tailed test, a claim that a parameter is greater than/ less than a value is being tested. i.e mean > value or mean < value.
Two tailed test: In a two tailed test, a claim that a value is equal to a value is tested, i.e mean = value.
In the question above, Colleen is testing the claim that the average score of her class is the same as others against that it is different from others.
Therefore, the null hypothesis is H0: mean = 514 while the alternative hypothesis is H1: mean ≠ 514
