A company with n employees publishes an internal calendar, where each day lists the employees having a birthday that day. What i

lutik1710 [3]

Answer: $1-(\frac{364}{365})^n$

Step-by-step explanation:

Binomial probability formula :-

$P(x)=^nC_xp^x(1-p)^x$ , where P(x) is the probability of getting success in x trials, n is the total number of trials and p is the probability of getting success in each trial.

We assume that the total number of days in a particular year are 365.

Then , the probability for each employee to have birthday on a certain day :

$p=\dfrac{1}{365}$

Given : The number of employee in the company = n

Then, the probability there is at least one day in a year when nobody has a birthday is given by :-

$P(x\geq1)=1-P(x$

Hence, the probability there is at least one day in a year when nobody has a birthday = $1-(\frac{364}{365})^n$

Living with parents: The Pew Research Center reported that 36% of American Millennials (adults ages 18-31) stll live at home wit

Lera25 [3.4K]

Answer:

A.

$\mathbf{The \ sample \ comes \ from \ a \ population \ of \ Millennial \ students }$ $\mathbf{at \ their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \ parents}$

Step-by-step explanation:

From the given information.

The proportion of American Millennials still with their parents = 0.36

The sample size = 300

Sample proportion = 0.43

Level of significance = 0.006

P-value = 0.006

Null hypothesis:

$\mathbf{H_o: Of \ Millennial \ students \ at \ their \ campus, \ 36\% \ }$ $\mathbf{ live \ at \ some \ with \ their \ parents . }$

$\mathbf{H_a: More \ than \ 36\% \ of \ Millennial \ students \ at \ their \ campus \ live \ at \ home }$ $\mathbf{ \ with \ their \ parents}$

The required task is to determine the assumption about the sample that underlies the hypothesis test from the given options.

A.

$\mathbf{The \ sample \ comes \ from \ a \ population \ of \ Millennial \ students }$ $\mathbf{at \ their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \ parents}$

This is because the student wants to check if the null hypothesis ( which states that of Millennial students at their campus, 36% live at home with their parents) is correct or not.
