I answered part b first before a, bec6 the answer to part b is what would aid me in answering part a
Answer:
B. The t test statistic is the appropriate test.
A. Reject the null hypothesis
Step-by-step explanation:
X1 = 6.841, sd1 = 0.155, n1 = 15
X2 = 6.701, sd2 = 0.108, n2 = 10
1. The appropriate test statistic for this question is the t test.
T = x1-x2/√sd1²/n1 + sd2²/n2
T = 6.841-6.701/√0.155²/15 + 0.108²/10
= 2.66
H0: u1 = u2
H1; u1>u2
Significance level = 0.05
Df = n1+n2-2
= 15+10-2
= 23
T critical = 1.714
2.66>1.714
So we have to reject the null hypothesis. Since we have enough evidence that supports this claim that fruit flavor bubble gum is on average, thicker than the fruit flavored gum.
Answer:
Step 2
Step-by-step explanation:
Jaime did not multiply by the reciprocal of 2/5 which is 5/2 on both sides.
5*5/2=25/2
The value of the inverse function at x = 32 will be 16. Then the correct option is D.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function.
The function is given below.
f(x) = 2x
Then the inverse function of the f(x) will be
2f⁻¹(x) = x
f⁻¹(x) = x / 2
Then the value of the inverse function at x = 32 will be
f⁻¹(32) = 32 / 2
f⁻¹(x) = 16
Then the correct option is D.
