Nicolas was testing
H0 : mu = 24
H0 : μ = 24
His test statistic was t = -1.79. Assume that the conditions for inference were met. What is the approximate P-value for Nicolas' test?
A. 0.0441.
B. 0.0505.
C. 0.0882.
D. 0.1010.
Answer:
B. 0.0505
Step-by-step explanation:
Test statistics technique is used to assess the condition whether to accept or reject the null hypothesis. Test statistics value is compared with the p-value in order to determine the status of null hypothesis. Nicolas test has t-value of 1.79 and degrees of freedom is assumed to be 11. The p-value for the Nicolas test is 0.0505.

how many solutions does this problem have 2x – 4 = 2(x – 2)
Answer:
= 0
Step-by-step explanation:
Let's solve your equation step-by-step.
2x−4=2(x−2)
Step 1: Simplify both sides of the equation.
2x−4=2(x−2)
2x+−4=(2)(x)+(2)(−2)(Distribute)
2x+−4=2x+−4
2x−4=2x−4
Step 2: Subtract 2x from both sides.
2x−4−2x=2x−4−2x
−4=−4
Step 3: Add 4 to both sides.
−4+4=−4+4

Explain the order in which you should compute the operations in the expression below.
[(33 / 3) + 1] - 2^2
1. You would divide the 33/3 first to get 11
2. Then you would add 1 to that answer to get 12
3. Then you would subtract 2^2 from that to get 8
Your answer would be 8.

Natural number are those number that is used for the purpose of counting and ordering. The two natural numbers are 4 and 6.
What are Natural numbers?Natural number are those number that is used for the purpose of counting and ordering. It is denoted by 'N'.
Let the first number(bigger number) be 'a', and the smaller number be b.
As it is given that the first number is 4 more than the second number. Therefore, the equation can be written as,
a = b + 4
Now, it is given that the product of the two numbers is three times the square of the smaller number. Since, when we add four to b we get a, therefore, b is the smaller number. Therefore, the equation can be written as,
[tex]ab = 3(b^2)\\[/tex]
As the value of a = b+4, substitute the value of a,
[tex](b+4)b = 3(b^2)\\\\(b+4) = \dfrac{3b^2}{b}\\\\b+4 = 3b\\\\4=3b-b\\\\4=2b\\\\b = 2[/tex]
Thus, the value of b is 2.
In order to get 'a' add 4 to the value of b, therefore, the value of a is,
[tex]a = b+4\\\\a = 2+4 \\\\a=6[/tex]
Hence, the two natural numbers are 4 and 6.
