Answer:
(y − 2)² / 16 − (x + 3)² / 36 = 1
Step-by-step explanation:
The conjugate axis is the axis of symmetry. The transverse axis is the line connecting the vertices of the hyperbola. Since the transverse axis is parallel to the y-axis, this is a vertical hyperbola:
(y − k)² / a² − (x − h) / b² = 1
where (h, k) is the center of the hyperbola, a is half the length of the transverse axis, and b is half the length of the conjugate axis.
Here, the center is (-3, 2), a = 8/2 = 4, and b = 12/2 = 6.
(y − 2)² / 16 − (x + 3)² / 36 = 1
Answer:
The pvalue of 0.0113 < 0.05 means that there is sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
A recent survey of 50 executives who were laid off during a recent recession revealed it took a mean of 26 weeks for them to find another position.
This means that
Assume the population standard deviation is 6.2 weeks.
This means that
Does the data provide sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance
We have to find the pvalue of Z, looking at the z-table, when . It if is lower than 0.05, it provides evidence.
has a pvalue of 0.0113 < 0.05.
The pvalue of 0.0113 < 0.05 means that there is sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance
