Answer:
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Step-by-step explanation:
We are given the following in the question:
Mean storage capacity = 60 ampere-hour
95% confidence interval =

Thus, the correct answer based on the confidence interval is
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Since it is a two sided test we test whether the mean storage capacity is 60 Ah or different than 60 Ah
Thus, the battery storage is different from 60 Ah because the mean storage capacity does not lie in the 95% confidence interval.
Answer: The required number of large order of chicken tenders is 5.
Step-by-step explanation: Given that Sheila loves to eat chicken tenders. A small order comes with 5 chicken tenders, and a large order comes with 8 chicken tenders.
Last month, Sheila ordered chicken tenders a total of 7 times. She received a total of 50 chicken tenders.
We are to find the number of large chicken tenders received by Sheila.
Let x and y represents the number of small orders and large orders respectively of chicken tenders.
Then, according to the given information, we have

and
![5x+8y=50\\\\\Rightarrow 5(7-y)+8y=50~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{Using equation (i)}]\\\\\Rightarrow 35-5y+8y=50\\\\\Rightarrow 3y=50-35\\\\\Rightarrow 3y=15\\\\\Rightarrow y=\dfrac{15}{3}\\\\\Rightarrow y=5.](https://tex.z-dn.net/?f=5x%2B8y%3D50%5C%5C%5C%5C%5CRightarrow%205%287-y%29%2B8y%3D50~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%5B%5Ctextup%7BUsing%20equation%20%28i%29%7D%5D%5C%5C%5C%5C%5CRightarrow%2035-5y%2B8y%3D50%5C%5C%5C%5C%5CRightarrow%203y%3D50-35%5C%5C%5C%5C%5CRightarrow%203y%3D15%5C%5C%5C%5C%5CRightarrow%20y%3D%5Cdfrac%7B15%7D%7B3%7D%5C%5C%5C%5C%5CRightarrow%20y%3D5.)
Thus, the required number of large order of chicken tenders is 5.
