LiRa [457]

Answer:

The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.

Step-by-step explanation:

We take the estimate from the website, and expand for all buyers, to find the proportion that use their smartphones.

400 users of the website were randomly sampled from the existing database and 180 were found to have used their smart phones.

180/400 = 0.45

The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.

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.
