The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.

garik1379 [7]

Answer:

The probability that X is less than 32 minutes is 0.736.

Step-by-step explanation:

Given : The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift. If X has an average value of 24 minutes.

To find : What is the probability that X is less than 32 minutes?

Solution :

If X has an average value of 24 minutes.

i.e. $\lambda=24$

The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.

The exponentially function is $\frac{1}{\lambda}e^{-\frac{x}{\lambda}}$

The function form according to question is

$f(x)=\{\frac{1}{24}e^{-\frac{x}{24}}, x>0\}$

The probability that X is less than 32 minutes is

$P[x$

Therefore, the probability that X is less than 32 minutes is 0.736.

A population contains six members, with values 1,1,2,3,5,10. A random sample of size 3 is drawn without replacement. Estimate th

Ronch [10]

Answer:

So, the population mean is 3.66.

Step-by-step explanation:

We will calculate the average value by summing all the values and dividing by the size of sample.

We have population contains six members, with values 1,1,2,3,5,10.

Therefore, n=6.

We use the formula to calculate the population mean:

$\mu=\frac{x_1+...+x_n}{n}\\\\\mu=\frac{1+1+2+3+5+10}{6}\\\\\mu=\frac{22}{6}\\\\\mu=3.66$

So, the population mean is 3.66.
