ive males with an​ X-linked genetic disorder have one child each. The random variable x is the number of children among the five

who inherit the​ X-linked genetic disorder. Determine whether a probability distribution is given. If a probability distribution is​ given, find its mean and standard deviation. If a probability distribution is not​ given, identify the requirements that are not satisfied. x ​P(x) 0 0.0290.029 1 0.1610.161 2 0.3100.310 3 0.3100.310 4 0.1610.161 5 0.0290.029 Does the table show a probability​ distribution? Select all that apply. A. ​Yes, the table shows a probability distribution. Your answer is correct.B. ​No, the sum of all the probabilities is not equal to 1. C. ​No, the random variable x is categorical instead of numerical. D. ​No, not every probability is between 0 and 1 inclusive. E. ​No, the random variable​ x's number values are not associated with probabilities. Find the mean of the random variable x. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice. A. muμequals=nothing ​child(ren) ​(Round to one decimal place as​ needed.)

A university with a high water bill is interested in estimating the mean amount of time that students spend in the shower each d
Bas_tet [7]

Answer: (4.0845,\ 6.5755)

Step-by-step explanation:

As per given , we have

n = 11

\overline{x}=5.33\\\\ s=1.33

Since population standard deviation is missing, so we use t-test.

Critical t-value for 99% confidence :

t_{\alpha/2,\ n-1}=3.106   [using two-tailed t-value table]

Confidence interval :

\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}\\\\= 5.33\pm (3.1060)\dfrac{1.33}{\sqrt{11}}\\\\\approx5.33\pm1.2455\\\\=(5.33-1.2455,\ 5.33+1.2455)\\\\=(4.0845,\ 6.5755)

Hence,  99% confidence interval for the mean amount of time that students spend in the shower each day.= (4.0845,\ 6.5755)

Likurg_2 [28]

Answer:

This differs from non-rigid motion, like a dilation, where the size of the object can increase or decrease. When working with rigid motion, you will typically see two objects that show the transformation.

The formula for the area of a circle is A = πr^2. Which equation shows the formula in terms of r?
Julli [10]
A=\pi r^2\\\\\pi r^2=A\ \ \  |\text{divide both sides by}\ \pi\\\\r^2=\dfrac{A}{\pi}\ \ \ \ |\text{square root both sides}\\\\r=\sqrt{\dfrac{A}{\pi}}
