Suppose that a sample of size 100 is to be drawn from a population with standard deviation L0. a. What is the probability that t

NARA [144]

Answer:

The probability that the sample mean will lie within 2 values of μ is 0.9544.

Step-by-step explanation:

Here

the sample size is given as 100
the standard deviation is 10

The probability that the sample mean lies with 2 of the value of μ is given as

$P(| \bar{X}-\mu|$

Here converting the values in z form gives

$P(-2$

Substituting values

$P(-2$

From z table

$P(z\leq 2)=0.9772\\P(z\leq -2)=0.0228\\P(-2\leq z\leq 2)=P(z\leq 2)-P(z\leq -2)\\P(-2\leq z\leq 2)=0.9772-0.0228\\P(-2\leq z\leq 2)=0.9544\\$

So the probability that the sample mean will lie within 2 values of μ is 0.9544.

What is the probability that a resident reports high satisfaction, given that the resident is a renter?

dem82 [27]

Answer:

The probability that a resident reports high satisfaction while the resident is a renter is Option(a) $13.7\%$

Step-by-step explanation:

Given:

Levels of satisfaction

High Medium Low Total

Owners $26$ $34$ $18$ $78$

Renters $15$ $12$ $5$ $22$

Total $41$ $46$ $23$ $110$

The Resident is a renter.

Step 1:

To find the probability that a resident reports high satisfaction.

P(Renter- higher satisfaction)= Higher Satisfaction by render ÷ Total level of satisfaction

$=\frac{15}{110}$

$=0.137$

$13.7\%$ is the probability that a resident reports high satisfaction.

Therefore, Option (a) is a correct answer.
