Answer:
A) y = is logarithmic function.
Step-by-step explanation:
Given : Options.
To find : which of the following is a logarithmic function.
Solution : We have given option
Logarithmic function : The function which have log init.
We can see from given options
y = is logarithmic function.
Therefore, A) y = is logarithmic function.
Answer:
Step-by-step explanation:
The confidence interval estimate for the population mean is given by :-
, where
is the sample mean and ME is the margin of error.
Given : Sample mean:
The margin of error for a 98% confidence interval estimate for the population mean using the Student's t-distribution :
Now, the confidence interval estimate for the population mean will be :-
Hence, the 98% confidence interval estimate for the population mean using the Student's t-distribution =
I'm assuming you want us to solve for the unknown variable z
Combine like terms on the right side
Use the distributive property on the left side
Add both sides by 20 to cancel out the "-20" on the left side
Divide both sides by 10
That is the value of the known variable, z, in this equation. Let me know if you need any clarifications, thanks!
