Answer:
X[bar]= 115
Step-by-step explanation:
Hello!
Every Confidence interval to estimate the population mean are constructed following the structure:
"Estimator" ± margin of error"
Wich means that the intervals are centered around the sample mean. To know the value of the sample mean you have to make the following calculation:
![X[bar]= \frac{Upper bond + Low bond}{2}](https://tex.z-dn.net/?f=X%5Bbar%5D%3D%20%5Cfrac%7BUpper%20bond%20%2B%20Low%20bond%7D%7B2%7D)
![X[bar]= \frac{115.6+114.4}{2}](https://tex.z-dn.net/?f=X%5Bbar%5D%3D%20%5Cfrac%7B115.6%2B114.4%7D%7B2%7D)
= 115
Since both intervals were calculated with the information of the same sample, you can choose either to calculate the sample mean.
I hope it helps!
Answer:
b. 13 hour, 20 min
Step-by-step explanation:
When it is 4:00 a.m. in Halifax, it is 1:00 p.m. in Karachi, this means Karachi is 9 hour ahead of Halifax.
When it is 9:00 a.m. in Karachi, it is 5:00 a.m. in Warsaw, this means that Warsaw is 4 hours behind Karachi.
She arrived to Karachi at 3:00 pm, Tuesday. Local time. When is 3:00 pm in Karachi is 11:00 am in Warsaw.
The difference between 9:40 am, Monday and 11:00 am, Tuesday, both in Warsaw local time is 13 hour 20 min.
