Answer:
The 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is (0.472,0.766).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
In a sample of 42 water specimens taken from a construction site, 26 contained detectable levels of lead.
This means that
95% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is (0.472,0.766).
Answer: The missing number in the sequence is
Step-by-step explanation:
Since we have given that
First term = a=
Common difference = d is given by
Therefore, it forms an arithmetic sequence.
Since, is missing,
So,
Hence, the missing number in the sequence is
