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.
