Answer: c. 3.01
Step-by-step explanation:
The test statistic for difference between two population mean (when population standard deviation is known) is given by :
, where = Size of first sample
= Size of second sample
= Difference between two sample mean.
= standard deviation for population 1.
= standard deviation for population 2.
As per given , we have
Substitute these values in formula , we get
Hence, the value of the test statistic is <u>3.01</u>.
Hence, the correct option is c. 3.01 .
Answer:
Horizontal asymptote of the graph of the function f(x) = 25/1+4x is y=0
Step-by-step explanation:
I attached the graph of the function. Graphically it can be seen that the horizontal asymptote of the graph of the function is y=0. There is also a <em>vertical</em> asymptote at x=-1/4
When denominator's degree (1) is higher than nominator's degree (0) then the horizontal asymptote is y=0
