Step-by-step explanation:

A statewide real estate sales agency, Farm Associates, specializes in selling farm property in the state of Nebraska. Its records indicate that the mean selling time of farm property is 90 days. Because of recent drought conditions, the agency believes that the mean selling time is now greater than 90 days. A statewide survey of 100 farms sold recently revealed that the mean selling time was 94 days, with a standard deviation of 22 days.

Required:
At the 0.10 significance level, has there been an increase in selling time?

Answers

Answer:

The right answer is "1.818".

Step-by-step explanation:

The given values are:

a = 0.1

[tex]\bar{x} = 94[/tex]

[tex]\mu = 90[/tex]

Now,

The test statistic will be:

⇒  [tex]t=\frac{\bar{x}-\mu}{\frac{s}{vn} }[/tex]

On substituting the given values, we get

⇒     [tex]=\frac{94-90}{\frac{22}{10} }[/tex]

⇒     [tex]=\frac{4}{2.2}[/tex]

⇒     [tex]=1.818[/tex]

Option 1

Step-by-step explanation:

In the first one, the first number is lower than -2, the second is between -1 and 0, and 1+1/6 is of course bigger than 0 and smaller than 1+5/6, so it's the right answer.

The second one is the first one reversed, so it's ordered from greatest to lowest.

The third one has a negative number on both ends, but positives in the middle, so it cannot be ordered lowest to greatest. Same with the last one.

Answer:

Function that fits the points [tex](0,5),\,(2,-13)[/tex] is given by [tex]x+9y=45[/tex]

Step-by-step explanation:

Let [tex](x_1,y_1)=(0,5),\,(x_2,y_2)=(2,-13)[/tex]

Slope of a line joining points [tex](x_1,y_1),\,(x_2,y_2)[/tex] is given by [tex]m=\frac{x_2-x_1}{y_2-y_1}[/tex]

[tex]=\frac{2-0}{-13-5}[/tex]
