Answer:
The p-value for this hypothesis test is P=0.015.
Step-by-step explanation:
In this case we have hypothesis test for the mean, with standard deviation of the population unknown.
The null hypothesis we want to test is
To work with this test we have a sample of size n=20, sample mean=91 and sample standard deviation=21.
First, we estimate the standard deviation of the population
Then, because we have an estimated standard deviation, we have to calculate the statistics t.
We can look up this value of t in a t-table to know the probability of this value, taking into account 19 degrees of freedom:
The p-value or the probability of P(t>2.342) is 0.01511.
This value P=0.0151 is compared to the significance level (0.05). Since the probability value (0.0151) is less than the significance level (0.05) the effect is statistically significant. Since the effect is significant, the null hypothesis is rejected.
The ends of the major axis is = (0, ± 13) and that of the foci is: (0,±5).
<h3>What is the axis and foci about?</h3>The term 'foci' is known to be the point at which there is the coming together of light or any other kinds of electromagnetic radiation, particles, etc.
It is also seen as the point from which they seems to go apart.
Hence, major axis is = (0, ± 13)
e =
= 5/13
Foci is: (0± 13 x )
Foci is: (0, ±5)
Therefore, The ends of the major axis is = (0, ± 13) and that of the foci is: (0,±5).
