A real estate agent believes that the value of houses in the neighborhood she works in has increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market value in the current year to their estimated market value in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. The agent uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈7.496, which has 7 degrees of freedom, determine the range that contains the p-value.

Answers

Answer 1

Answer:

The range is  [tex]-0.00007 < p-value < 0.00007[/tex]

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  8

    The null hypothesis is  [tex]H_o : \mu_d = 0[/tex]

     The alternative hypothesis is  [tex]H_a : \mu_d > 0[/tex]

      The test statistics is  [tex]z \approx 7.496[/tex]

      The degree of freedom is  [tex]df = 7[/tex]

Generally the p-value is mathematically represented as

       [tex]p-value = P(Z > 7.496 )[/tex]

Generally from the t distribution table

(Reference  -

danielsoper(dot)com(slash)statcalc(slash)calculator)  

the value of  [tex]P(Z > 7.496 )[/tex] at a degree of freedom 7 is

      [tex]P(Z > 7.496 ) = t_{7.496 , 7 } =0.00007[/tex]

So the range that contains the p -value is  

        [tex]-0.00007 < p-value < 0.00007[/tex]

Answers

Answer:

Step-by-step explanation:

Answer:

Y = 8

Step-by-step explanation:

To solve this equation, you must isolate the variable (y).

To do this, let's add 15 to both sides.

-15+3y = 9

+15         +15

3y = 24

Then, we need to divide each side by 3, in order to get y alone.

One-fifth of an even number added to one-sixth of the next even number makes a total of 15. find the two numbers​
(Hint: let the number be x and x + 2.)

Answers

Answer:

40 and 42

Step-by-step explanation:

Let the two even numbers be x and x+2.

"One-fifth of an even number:"  (1/5)x

"one-sixth of the next even number:"  (1/6)(x+2)

Added they make 15:  (1/5)x + ((1/6)(x+2)) = 15

(1/5)x + ((1/6)(x+2)) = 15

(1/5)x + (1/6)x+(1/6)*2 = 15

(1/5)x + (1/6)x+(2/6) = 15

(6/30)x + (5/30)x = 15 - (1/3)

(11/30)x = (45/3) - (1/3)

(11/30)x = (44/3)

x = (30/11)*(44/3)

x = 40

x + 2 = 42

(1/5)(40) + (1/6)(42) = 15?

Answers

Answer:

d. {(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}; Domain: {-2, -1, 0, 1, 2}; Range: {1, 2, 5}

Step-by-step explanation:

Part A:

Domain = the set of all x-values plotted on the x-axis = {-2, -1, 0, 1, 2}

Range = the set of all possible y-values on the y-axis that corresponds with the x-values = {1, 2, 5}

Part B:

The set of coordinates that describes the function on the graph are:

When x = -2, y = 5 => (-2, 5)

When x = -1, y = 2 => (-1, 2)

When x = 0, y = 1 => (0, 1)

When x = 1, y = 2 => (1, 2)

When x = 2, y = 5 => (2, 5)

The set of coordinates is:

{(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}

supposed normal distribution has a mean of 89 and a standard deviation of 7. What is P(x≤82)? NO LINKS!!!

a. 0.975
b. 0.84
c. 0.16
d. 0.025​

Answers

Answer:  C)  0.16

======================================================

Explanation:

Convert the x = 82 to a corresponding z score.

z = (x-mu)/sigma

z = (82 - 89)/7

z = -7/7

z = -1

Using the empirical rule (see chart below), roughly 68% of the distribution is within 1 standard deviation of the mean.

This leaves 1 - 0.68 = 0.32 = 32% of the distribution in both tails, and (32%)/2 = 16% of the area is in one tail, which converts to 0.16

About 16% of the normally distributed population is below z = -1.

So we can say [tex]P(x \le 82) = P(z \le -1) \approx 0.16[/tex]

Mean=[tex]\overline{x}[/tex]=89Standard deviation=[tex]\sum[/tex]=7

x is 82

z value:-

[tex]\\ \rm\Rrightarrow \dfrac{x-\overline{x}}{\sum}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{82-89}{7}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{-7}{7}[/tex]

[tex]\\ \rm\Rrightarrow -1[/tex]

z=-1

As per z value chart

Part distributed to z=-1 is 32%/2=16%=0.16
