Answer:
155
Step-by-step explanation:
As the diagram shows, it looks the same as the other side. In, that case it would be the same so 155.
Answer:
Both have mid value of interval as mean =2.98
Step-by-step explanation:
Given that a survey of 25 grocery stores revealed that the mean price of a gallon of milk was $2.98, with a standard error of $0.10.
We have Margin of error = * Std error
The critical values for z are as per table below:
<u>Confidence level Z critical Margin of error</u>
90% 1.645
95% 1.96
Mean of milk galon = 2.98
Confidence interval = ±Margin of error
CI 90% =
CI 95% =
Similarities are both have mid value the same as 2.98
The following is an expression.
