Answer:
D) The z-statistics would be different.
Step-by-step explanation:
Confidence Interval can be calculated using M±ME where
- M is the sample mean
- ME is the margin of error from the mean
An margin of error (ME) from the mean can be calculated using the formula
ME= where
- z is the corresponding z-statistic in the given confidence level
- s is the population standard deviation
- N is the sample size
If 95% and 98% confidence intervals were calculated from the same sample data, then M, s and N are same.
is called standard error. Since s and N are same the standard errors would also be same.
But, two tailed z-statistic for 95% confidence level is ≈1.96 where for 98% it is ≈2.33
Answer: (2.6, 0.4), (3.6,0.6) is the solution of given equations.
Explanation: Given Functions are:
f(x)=log(x) and g(x)=|x-3|
Since, the solution of the above equations will be get after solving these two equations. Or we can say that, the intersection point of the curves made by the above equation is the solution of the system.
After making the graph of functions f(x) and g(x) we observed that, f(x) and g(x) are intersecting at points (2.587, 0.413) ≈(2.6,0.4) and (3.55,0.55)≈(3.6,0.6).
Thus, solution of f(x) and g(x) are (2.6,0.4) and (3.6,0.6).
Therefore, options first and fourth is correct.
