gogolik [260]

Answer:

There are 3060 apples in the shipment.

Step-by-step explanation:

Given:

Number of boxes of apples = 15

Each boxes contains = 17 bags of Apples

hence 15 boxes will contains = Number of bags of apples in 15 boxes.

By Using Unitary Method we get;

Number of bags of apples in 15 boxes = $15\times 17= 255 \ bags \ of \ apples$

Hence 15 boxes contains = 255 bags of apples.

Also Given:

Each bag contains = 12 apples

255 bags contains = Number of apples in 255 bags

By Using Unitary Method we get;

Number of apples in 255 bags = $255\times12= 3060 \ apples$

Hence 255 bags of apples contains = 3060 apples.

Hence There are 3060 apples in the shipment.

The administrators at the University of Oklahoma wonder if Oklahoma residents or non-Oklahoma residents differ in their exciteme

densk [106]

Answer:

d. The administrators are unable to tell if there is a true difference between Oklahoma and non-Oklahoma residents in their excitement to go home for the holidays because their interval covers 0.

Step-by-step explanation:

The confidence interval refers to a rabje of statistically calculated values used in establishing a certain level of confidence in the outcome of a data.

The confidence interval is calculated thus :

Mean ± (Zcritical * Error)

The ± sign ensures we have the lower and upper boundary of our confidence level.

From the confidence level given in the question : -1.78 to 3.27

Since 0 is contained in the confidence interval range given, then it can be concluded that the difference in excitement between Oklahoma and non oklahoma residents cannot be adequately established.
