The hypothesis testing for this problem is:
a. The hypothesis for this problem are:
Null: H0: μ=6
Alternative: Ha: μ≠6
b. Test
T-statistics = (6.08 - 6) / 0.44* √(121) = 2
c. P value = 0.047759
Since our p-value is smaller than the significant level of 0.05, we can say that we reject the null hypothesis.
Conclusion: there is enough evidence to say lathe is not in perfect adjustment.
Answer:
x = 8
Step-by-step explanation:
Step 1: Write equation
2(x + 5) = 26
Step 2: Solve for <em>x</em>
<u>Distribute 2:</u> 2x + 10 = 26
<u>Subtract 10 on both sides:</u> 2x = 16
<u>Divide both sides by 2:</u> x = 8
Answer:
Step-by-step explanation:
23
This is an expontential growth, which is a growth based on f(x) = b*a^x
b = 1500
a = 1.03
x = 3
f(3)=1500*1.03^3 = 1639.10$
After three years the fridge would cost 1639.1$.
