The following observations on degree of polymerization for paper specimens are used to estimate the true average degree polymeri

marshall27 [118]

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.

| 7 + m | - 4 > 8

cestrela7 [59]

Answer:

m > 5 or m < -19

Step-by-step explanation:

We are given the Inequality:

$\displaystyle \large{ |7 + m| - 4 > 8}$

First, add both sides by 4.

$\displaystyle \large{ |7 + m| - 4 + 4 > 8 + 4} \\ \displaystyle \large{ |7 + m| > 12}$

Absolute Value Property

$\displaystyle \large{ |a| = \sqrt{ {a}^{2} } }$

Given a = any expressions and b = any positive numbers, zero or any expressions.

$\displaystyle \large{ |a| = b \longrightarrow a = \pm b}$

From the Inequality, change > to equal

$\displaystyle \large{ 7 + m = \pm12}$

Subtract 7 both sides.

$\displaystyle \large{ 7 - 7 + m = \pm12 - 7} \\ \displaystyle \large{ m = \pm12 - 7}$

±12-7 can be 12-7 = 5 or -12-7 = -19

$\displaystyle \large{ m = 5, - 19}$

Refer to the attachment. The region is when the absolute value function is greater than constant function y = 12 or a blue horizontal line.

Since the absolute graph is above constant graph when x > 5 and x <-19.

Therefore,

$\displaystyle \large{ m > 5, m < - 19}$
