A statistical study reported that a drug was effective with a p-value of .042.

Mathematics

loris [4]3 years ago

Answer:

(a) An ineffective sample may be found about 42 times in 1000 samples.

(b) Yes, the drug is evidently effective at alpha = 0.05.

(c) A drug that had a p-value of 0.042 is more effective in comparison to a drug that had a p-value of 0.087.

Step-by-step explanation:

We are given that a statistical study reported that a drug was effective with a p-value of 0.042.

Let the Null Hypothesis, H_0 : The drug was ineffective.

Alternate Hypothesis, H_A : The drug was effective.

(a) An ineffective sample may be found about 42 times in 1000 samples.

(b) As we know that, if the P-value is less than the level of significance, then we have sufficient evidence to reject our null hypothesis.

SO, here also; the P-value is less than the level of significance as 0.042 < 0.05, so we reject our null hypothesis and conclude that the drug is evidently effective.

(c) The drug that had a p-value of 0.087 would be ineffective as in this case the P-value is more than the level of significance as 0.087 > 0.05, so we do not reject our null hypothesis and conclude that the drug is evidently ineffective.

This means that a drug that had a p-value of 0.042 is more effective in comparison to a drug that had a p-value of 0.087.

Write a number in each blank to complete each equation so that it has the requested number of solutions. a. Equation with no sol
Setler79 [48]

Answer:

The answer is  8x - 3x + 2 -x =<u> 4 </u>x + <u>2 </u> .

Step-by-step explanation:

Given:

8x - 3x + 2 -x = __ x + __

Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.

So, to solve the equation:

8x-3x+2-x

So, we add  the variables:

5x+2-x

And, then subtract it:

4x-2.

Thus, it remains:

4x-2.

So the complete equation is:

8x - 3x + 2 -x =<u> 4 </u>x + <u>2 </u>

Therefore, the answer is  8x - 3x + 2 -x =<u> 4 </u>x + <u>2 </u> .

2m3 of soil containing 28% silt was mixed into 1 m3 of soil containing 13% of silt. What is the silt content mixture?
Leto [7]
Alright
so
28% of 2 m³=0.28 times 2=0.56 m³ of silt in the first mixture

13% of the 1 m³=0.13 times 1=0.13 m³ of silt in 2nd

total is 0.56 m³+0.13 m³=0.69 m³ of silt
and the total is 2m³+1m³=3m³

so
0.69/3=0.23=23%

answer is D

Write an expression for the sequence of operations described below. multiply 3 by t, triple the result, then raise what you have
Nadusha1986 [10]

Answer: 43046721(t^8)

Step-by-step explanation:

So first, multiply 3 by t to get 3t. Then, multiply it again by 3 to get 9t. Raise it to the 8th power to get (9^8)(t^8). This gives you 43046721(t^8)
