Answer:

Positive where x < -6 and x > 8.

Step-by-step explanation:

y = x^2 - 2x - 48

The graph of this is a parabola which opens upwards ( because the coefficient of x^2 ( = 1) is positive). So it will positive to the left and to the right of the points where it passes through the x axis ( i e the zeros of the function).

x^2 - 2x - 48 =0

(x + 6)(x - 8) = 0

So the zeros are at x = (-6,0) and at (8, 0).

Therefore the intervals are x < -6 and x > 8.

Answer: Correct critical value = 2.2622

Step-by-step explanation:

Confidence interval for population mean when population standard deviation is unknown:

$\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}$ , where $\overline{x}$ = sample mean, n= sample size, s= sample standard deviation, $t_{\alpha/2}$ = two-tailed t value.

As per given: n= 10

degree of freedom : df = n-1=9

$\overline{x}=242.6\\\\s=73.33\\\\\alpha=5\%=0.05$

Critical t-value : $t_{\alpha/2,df}=t_{0.05/2,9}=t_{0.025,9}=2.2622$

So, the 95 percent confidence interval estimate for the mean :

$242.6\pm (2.2622)\dfrac{73.33}{\sqrt{10}}\\\\=242.6\pm (2.2622)(23.19)\\\\\approx242.6\pm52.46\\\\=(242.6-52.46,\ 242.6+52.46)\\\\=(190.14,\ 295.06)$
