A=3+b. That is a reasonable expression, because a= the sum of 3 and b, an unknown number.
Answer:
μ > 21.21
Test statistic = 1.217
Kindly check explanation for more details
Step-by-step explanation:
The null hypothesis, H0 : μ = 21.21
Alternative hypothesis, H1 : μ > 21.21
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(21.212 - 21.21) ÷ (0.01 / √2)
= 1.217
The critical value :
From the t distribution :, one tailed = 2.434
Decision region :
Reject H0 if test statistic > critical value
1.217 < 2.434 ; We fail to reject the null ` ; and conclude that there is not enough evidence to support the claim.
From the equation, we can tell that left side of the equation has to be less than or equal to 6 in order for the equation to be true.
So first, let’s try n=0.
Plug it in: 2(0)=0 and since 0 is less than 6, it makes the equation true.
Next, let’s try 1. 2(1)=2. This also makes the equation true.
Next, let’s do n=3. 2(3)=6. So this also makes the equation true.
So the answers are:
n=0 , n=1 , and n=3
