Answer:
Statistics makes possible the translation of data into information about causes and effects, health risks and cures. powerful and valuable indicator. The data collected through Vital Statistics system and other methods must be converted into rates if they are to be useful for many public health purposes.
ABD is the supplement of DBC, so it is equal to 180-130= 50 degrees.
If BE is the bisector, then it splits the angle in half evenly. 50/2=25 degrees for EBA and DBE each.
Final answer: 25 degrees
i think your answer is 201 because 3 times 67 is 201.
<h2><u>
Answer with explanation:</u></h2>
Formula to find the confidence interval for population mean :-
, where = sample mean.
t*= critical z-value
n= sample size.
s= sample standard deviation.
By considering the given question , we have
n= 50
Degree of freedom : df = 49 [ df=n-1]
Significance level :
Using students's t-distribution table, the critical t-value for 95% confidence =
Then, 95% confidence interval for the population mean will be :
Hence, a 95% confidence interval for the population mean = (24.24, 27.76)
Since 28 is not contained in the above confidence interval , it means it is not reasonable that the population mean is 28 weeks.
