Answer:
A. No, the hypothesis test was conducted correctly, and the correct conclusion was made.
Step-by-step explanation:
Given that the head of institutional research at a university believed that the mean age of full-time students was declining. In 1995,the mean age of a full-time student was known to be 27.4 years.
For this he has recorded all 4934 students and got average as 27.1 years
This is very much perfect because the question is about the mean age of a full time student. when all full time students in the university are taken into account and mean arrived this is a reliable procedure.
The hypothesis also is right as this is left tailed test.
Since p =0.002<0.05 he rejected null hypothesis.
Conclusion is the mean age did decline. Everything is right.
A. No, the hypothesis test was conducted correctly, and the correct conclusion was made.
Answer:
54 Degrees
Step-by-step explanation:
We know that the interior angles of a triangle add up to 180 degrees.
we also know that angle KLM = 48 degrees
and angle JKM = 78 degrees
since these triangles are on parallel lines we know that their angles must be equal (just inverted)
and thus:
180 - (48+78) = 54
<span>To find the exact calculator experence to find the exact value of a coterminal angle to a given trigonometric angle. Since there are an infinite number of coterminal angles, this calculator finds the one whose size is between 0 and 360 degrees or between 0 and 2π depending on the unit of the given angle.</span>
Answer:
it would be 5,4
Step-by-step explanation:
go to 5 the to 4 wich would then lead you to 5,4
