Answer: We reject the null hypothesis, and we use Normal distribution for the test.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis : 
Alternate hypothesis : 
There is 5% level of significance.

So, the test statistic would be

Since alternate hypothesis is left tailed test.
So, p-value = P(z≤-2.31)=0.0401
And the P-value =0.0401 is less than the given level of significance i.e. 5% 0.05.
So, we reject the null hypothesis, and we use Normal distribution for the test.

Answer:
x= -1/3
Step-by-step explanation:
2x+7x=-3
9x/9= -3/9
x = -1/3
Answer:
Volume A= one third
Step-by-step explanation:
Use volume B
Let's call the number x. Now, let's make an equation to help us solve this problem.
(((0.43+x)-.58)-4.04) = 30.3
(0.43+x)-4.64 = 30.3
x-4.21 = 30.3
x = 30.3 + 4.21
x = 34.51
The answer is 34.51 and there's the work for you. Have a great day!
