Answer:
The answer is D. y = −6.6 and y = 10.6
Step-by-step explanation:
First of all, this is an ellipse with a vertical major axis so it would have to be y = #
d=a2/c
d is the distance between the center and the directrix.
a= 8 b=3
c2=a2-b2
=64-9
c2=55
= about 7.4
d=64/7.4
=8.6
y= 2+8.6
<u>y=10.6</u>
y=2-8.6
<u>y=-6.6</u>

Answer:
0.8333
Step-by-step explanation:
Given that a group of statistics students conducted a random sample of 64 students at their college.
Their findings showed that the sampled students studied an average of 15 hours per week with a standard deviation of 5 hours
i.e we have
sample size = ![n=64](https://tex.z-dn.net/?f=n%3D64)
Standard deviation of sample s = ![5](https://tex.z-dn.net/?f=5)
By central limit theorem we have sample mean will follow a normal distribution with mean = sample mean and std error = std deviation /square root of n.
Substitute the values to get
Standard error of means =
