P(m1) 26/46 for pick on.. but that removed one male from the population and also one from the total
P(m2) 25/45
now multiply those two fractions together to get the total probability
26/46 * 25/45 = 650/2070 obviously reduce fraction

The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 4.50 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 53 randomly selected calls. The mean wait time was calculated to be 4.94 minutes. Assuming the population standard deviation is 2.10 minutes,
Required:
a. Is there sufficient evidence to say that the mean wait time for customers is longer than 4.50 minutes with a 98% level of confidence?
b. State the null and alternative hypotheses for the test.
Answers
Answer:
a) The lower bound of the confidence interval is below 4.50 minutes, which means that there is not sufficient evidence to say that the mean wait time for customers is longer than 4.50 minutes with a 98% level of confidence.
b) The null hypothesis is [tex]H_0: \mu \leq 4.50[/tex], and the alternate hypothesis is [tex]H_a: \mu > 4.50[/tex]
Step-by-step explanation:
Finding the confidence interval:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.01 = 0.98[/tex], so Z = 2.327.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.327\frac{2.1}{\sqrt{53}} = 0.67[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 4.94 - 0.67 = 4.27 minutes
The upper end of the interval is the sample mean added to M. So it is 4.94 + 0.67 = 5.61 minutes.
a. Is there sufficient evidence to say that the mean wait time for customers is longer than 4.50 minutes with a 98% level of confidence?
The lower bound of the confidence interval is below 4.50 minutes, which means that there is not sufficient evidence to say that the mean wait time for customers is longer than 4.50 minutes with a 98% level of confidence.
b. State the null and alternative hypotheses for the test.
Testing if there is evidence to say that the mean wait time for customers is longer than 4.50 minutes, which is the alternate hypothesis.
So the null hypothesis is [tex]H_0: \mu \leq 4.50[/tex], and the alternate hypothesis is [tex]H_a: \mu > 4.50[/tex]

[tex]\sqrt{(9-6)^{2}+([-1]-5)^{2}}[/tex] Plug in

Use the distance formula to find DA:

ND = [tex](3\sqrt{5}[/tex]
AL = 9
DA = [tex]3\sqrt{17}[/tex]
P = LN + ND + AL + DA Perimeter = sum of the measures of all sides
P = 9 + [tex](3\sqrt{5}[/tex] + 9 + [tex]3\sqrt{17}[/tex]

Find the value of x.
Answers
Answer:
x = 33
Step-by-step explanation:
Like the previous question we are going to imagine that the only angle there is angle "x"
Angle "x" is now an inscribed angle and it's intercepted arc has a measure of 66 degrees.
Now remember that an inscribed angle is equal to half of its intercepted arc.
This means that x = half of 66
[tex]\frac{66}{2} =33[/tex]
Hence, x = 33

Suppose that the TSH (Thyroid Stimulating Hormone) levels among healthy individuals are normally distributed with a mean of 3.3 unitsmL. Suppose also that exactly 98% of healthy individuals have TSH levels below 5.9 unitsmL. Find the standard deviation of the distribution of TSH levels of healthy individuals. Carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal plac
Answers
Answer:
The standard deviation of the distribution of TSH levels of healthy individuals is of 1.2658 units/mL.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 3.3 units/mL
This means that [tex]\mu = 3.3[/tex]
Suppose also that exactly 98% of healthy individuals have TSH levels below 5.9 units/mL.
This means that when [tex]X = 5.9[/tex], Z has a pvalue of 0.98. So Z when X = 5.9, has a pvalue if 0.98, that is, Z = 2.054. We use this to find [tex]\sigma[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.054 = \frac{5.9 - 3.3}{\sigma}[/tex]
[tex]2.054\sigma = 2.6[/tex]
[tex]\sigma = \frac{2.6}{2.054}[/tex]
[tex]\sigma = 1.2658[/tex]
The standard deviation of the distribution of TSH levels of healthy individuals is of 1.2658 units/mL.
