Answer:

The answer is "Type 1 error".

Step-by-step explanation:

The error of type I, frequently known as a 'false positive': its error in judgment that perhaps a null hypothesis is simply rejected. This is the mistake of accepting a possible (actual interest hypothesis) hypothesis whenever the results could be attributed to chance since the researchers deny, if valid, the null hypothesis.

Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (Enter your answers as a comma-
Shtirlitz [24]

Answer:

The number c is 2.

Step-by-step explanation:

Mean Value Theorem:

If f is a continuous function in a bounded interval [0,4], there is at least one value of c in (a,b) for which:

f(c) = \frac{1}{b-a}\int\limits^a_b {f(x)} \, dx

In this problem, we have that:

f(x) = x, a = 0, b = 4

So f(c) = c

----------

f(c) = \frac{1}{b-a}\int\limits^a_b {f(x)} \, dx

c = \frac{1}{4-0}\int\limits^0_4 {x} \, dx

c = \frac{1}{4-0}*8

c = 2

The number c is 2.
