One of the many concerns of college students today is the time required for them to graduate with a baccalaureate degree (BA or

uysha [10]

Answer:

The correct option is C.

Step-by-step explanation:

Given information:

$\overline{x}_1=4.95$

$\overline{x}_2=5.22$

$s_1=0.64$

$s_2=0.89$

$n_1=n_2=21$

The formula for t test statistic t* is

$t^*=\frac{(\overline{x}_1-\overline{x}_2)-(\mu_1-\mu_2)}{\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}}$

Using the formula we get

$t^*=\frac{\left(4.95-5.22\right)-(0)}{\sqrt{\frac{0.64^2}{21}+\frac{0.89^2}{21}}}$

$t^*=-1.12869182873$

$t^*\approx -1.13$

The value of test statistic t* is -1.13. Therefore the correct option is C.

kirza4 [7]

Answer:

A=640.88

Step-by-step explanation:

if the diameter is 12, the radius , r=12/2=6

we have r=6, h=11

Surface area, A= 2πrh+2π r^2

A=2*3.14*6*11+2*3.14*(6)^2=640.88
