Answer:

The answer is in the explanation

Step-by-step explanation:

Mean value = \bar x = 438

(a) The data appeared to be centered towards 438.

There are little or no skew.

There is no outliers.

(b) yes

(c) standard deviation = s = 14.8955

95% confidence interval = +- t_{df}  * s\sqrt{n}

    438 +- 2.12 * 14.8955 /\sqrt{17}=

= (430.3415, 445.6585)

(d) Test statistic

t = (438 - 450)/{14.8955\sqrt17} }

t = -3.3216

p -value is correctly given in option b.

No, 450 is not a plausible valaue.

Miriams house has a markey value of 125,000. The tax accessory evaluated her property tax rate to be 42%. What is the assessed v
MakcuM [25]
If you use the formula it states Assessed Value = Market Value x Rate.
Assessed value = 125000
Rate = 42In addition to the rate, you must divide 42 by 100, which makes .42 then add 1.
42/100 = 0.42 + 1 = 1.42
125000(1.42) = 177500
$177,500 is Miriam's assessed value of her house.

The length of one leg of a right triangle is 8 centimeters shorter than the
ra1l [238]

{34}^{2}  +  {b}^{2}  = {42}^{2}  \\ 1156 + {b}^{2}  = 1764 \\ 1156 - 1156 +  {b}^{2}  = 1764 - 1156 \\  {b}^{2}  = 608 \\  \sqrt{ {b}^{2} }  =  \sqrt{608}  \\ b = 24.7
I used the Pythagorean formula, which is a² + b² = c².
a² and b² are the two side legs while c² is the hypotenuse.
One of the side is 42 - 8 = 34 cm.
