Answer:
Tristan has a 17/24 lb fraction of a pound of grapes now.
Step-by-step explanation:
Given
- The number of grapes Tristan had at home = 1/3 lb
- The number of grapes Tristan had at the store = 3/8 lb
To determine
What fraction of a pound of grapes does Tristan have now?
In order to get the total fraction of a pound of grapes, all we need is to add the number of grapes Tristan had at home and the number of grapes Tristan had at the store.
i.e.
Current number grapes = 1/3 + 3/8
Least Common Multiple of 3, 8: 24
Adjust fractions based on L.C.M
= 8/24 + 9/24
Apply the fraction rule:
= (8 + 9) / 24
= 17/24 lb
Therefore, Tristan has a 17/24 lb fraction of a pound of grapes now.
Answer:
Step-by-step explanation:
From the given information:
The null hypothesis is:
The alternative hypothesis is:
The sample size n = 35
Sample mean = 7.91
variance = 0.03
Standard deviation =
The t-test statistics is computed as:
t = - 3.0741
Degree of freedom:
df = n - 1
df = 35 - 1
df = 34
Level of significance = 1 - C.I
= 1 - 0.99
= 0.01
The t_{critical} value for the two-tailed test at 0.01 is within the rejection region:
Decision rule: To reject if
As fails the rejection region, we reject
Conclusion: There is sufficient evidence to believe that the machine will not dispense 8 ounces & and it must be stopped for repairs.
