AC variant of the gene ACTN3 which inhibits fast-twitch muscles and seems to be less prevalent in sprinters has been studied. A

separate study1 indicated ethnic differences: Approximately 20% of a sample of Caucasians, approximately 25% of a sample of Asians, and approximately 1% of a sample of Africans had the gene variant. One variable is whether or not the gene variant is present and the other is which of the three ethnic groups the individual belongs to.

Answer:

Category variable: Caucasians, Asians, Africans

Quantitative variable: 20%, 25%, 1%.

Explanation: The are two variables in these study. They are categorical variable and quantitative variable.

Categorical variables are variable that helps classify a given population eg race, hair colour, skin colour. Most of the time are not numerical, so we can't multiply, add or subtract them. As given in this assignment the Caucasians, Asians and Africans are category variables.

Quantitative variables are those that numerical and they reflect count, percentages(20%, 25%, 1%) and can be added, subtracted, or multiplied. The percentage of the ethnic group is an example of quantitative variable.

On March 1st, Mr. Smithe signed up for a fitness program at Fit Co. and paid $960 for the entire program upfront. The program in
vichka [17]

Answer:

Revenue - March = $160

Explanation:

The accrual principle in accounting states that the revenues for a period should match the expenses for that particular period and any revenue or expense should be recorded in the period to which it relates to. This means that the upfront fee received by Fit Co. is a liability and should not be recorded as a revenue until it is earned. So, by providing two sessions in the month of March, Fit Co. has earned revenue for 2 sessions out of the twelve. Thus, at the end of March, Fit Co. should record a revenue of,

Revenue - march = 960 * 2/12 = $160

IgorLugansk [536]

Answer:

a) P(X \leq 2)= P(X=0)+P(X=1)+P(X=2)

P(X=0)=(11C0)(0.5)^0 (1-0.5)^{11-0}=0.00049

P(X=1)=(11C0)(0.5)^1 (1-0.5)^{11-1}=0.0054

P(X=2)=(11C0)(0.5)^2 (1-0.5)^{11-2}=0.027

And adding we got:

P(X \leq 2)= 0.033

b) P(X \geq 2)= 1-P(X

And replacing we got:

P(X \geq 2)= =1-[0.00049 +0.0054] = 0.994

c) P(X \leq 1)= 1-P(X

And replacing we got:

P(X \leq 1)=0.00049 +0.0054= 0.0059

Explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest "number of women", on this case we now that:

X \sim Binom(n=11, p=0.5)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

Part a

For this case we want to find this probability:

P(X \leq 2)= P(X=0)+P(X=1)+P(X=2)

P(X=0)=(11C0)(0.5)^0 (1-0.5)^{11-0}=0.00049

P(X=1)=(11C0)(0.5)^1 (1-0.5)^{11-1}=0.0054

P(X=2)=(11C0)(0.5)^2 (1-0.5)^{11-2}=0.027

And adding we got:

P(X \leq 2)= 0.033

Part b

For this case we want this probability:

P(X \geq 2)

And we can use the complement rule and we got:

P(X \geq 2)= 1-P(X

And replacing we got:

P(X \geq 2)= =1-[0.00049 +0.0054] = 0.994

Part c

For this case we want this probability:

P(X \leq 1)

And we can use the complement rule and we got:

P(X \leq 1)= 1-P(X

And replacing we got:

P(X \leq 1)=0.00049 +0.0054= 0.0059
