A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten y

lyudmila [28]

Answer: $69811

Step-by-step explanation:

Given : A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants.

One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920. (1)

We know that the confidence interval is given by :-

Point estimate of mean ± Margin of error

From (1) , we have

Point estimate for mean -Margin of error = $69,702 (2)

Point estimate for mean +Margin of error = $69,920 (3)

Add (2) and (3), we get

2 (Point estimate for mean) = $139622

Divide both sides by 2, we get

Point estimate for mean=$ 69811

Therefore , the point estimate for mean U.S. household income. = $ 69811

g Make a decision about the given claim. Use only the rare event rule, and make subjective estimates to determine whether event

vagabundo [1.1K]

Answer:

There is not sufficient evidence to support the claim.

Step-by-step explanation:

The claim to be tested is:

The mean respiration rate (in breaths per minute) of students in a large statistics class is less than 32.

To test this claim the hypothesis can be defined as follows:

<em>H₀</em>: The mean respiration rate of students is 32, i.e. <em>μ</em> = 32.

<em>Hₐ</em>: The mean respiration rate of students is less than 32, i.e. <em>μ</em> < 32.

The sample mean respiration rate of students is 31.3.

According to the claim the sample mean is less than 32.

The sample mean value is not unusual if the claim is true, and the sample mean value is also not unusual if the claim is false.

Thus, there is not sufficient evidence to support the claim.

viktelen [127]

Answer:

Ir is impossible to tell.

Step-by-step explanation:

We are given that,

Stan earns $15 on Monday, $45 on Tuesday, Wednesday and Thursday and $60 from Monday to Friday this week.

Since, we do not have the individual earnings for each day, we are unable to plot the graph of the given relationship.

So, without graph it is impossible to state whether the relationship is linear or not.
