Answer: the value of the test statistic is 2.11
Step-by-step explanation:
Given that;
sample mean x" = 95
standard deviation σ = 3
sample size n = 40
Null hypothesis H₀ : μ = 94
Alternative hypothesis H₁ : μ ≠ 94
Level of significance ∝ = 0.02
Test statistic value
z = (x" - μ) / ( σ/√n)
we substitute
z = (95 - 94) / ( 3/√40)
z = 1 / 0.4743
z = 2.11
Therefore, the value of the test statistic is 2.11
36 = 0.8% 36/8=4.5 4.5•10=45 45•10=450 your answer is 450
First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

Using this, we can multiply the 7 out to the
and 3. This gives us:

Now, let's solve for
:



We can see that there is one solution for this equation because
is equal to one definite value after solving. Thus, our answer is A, one solution.
