Is there any systematic tendency for part-time college faculty to hold their students to different standards than do full-time f
alexandr1967 [171]

Answer:

H0 : μ1 - μ2 = 0

H1 : μ1 - μ2 ≠ 0

-1. 34

0.1837

Step-by-step explanation:

Full time :

n1 = 125

x1 = 2.7386

s1 = 0.65342

Part time :

n2 = 88

x2 = 2.8439

s2 = 0.49241

H0 : μ1 - μ2 = 0

H1 : μ1 - μ2 ≠ 0

Test statistic :

The test statistic :

(x1 - x2) / sqrt[(s1²/n1 + s2²/n2)]

(2.7386 - 2.8439) / sqrt[(0.65342²/125 + 0.49241²/88)]

−0.1053 / sqrt(0.0034156615712 + 0.0027553)

-0.1053 /0.0785554

= - 1.34

Test statistic = - 1.34

The Pvalue :

Using df = smaller n - 1 = 88 - 1 = 87

Pvalue from test statistic score ;

Pvalue = 0.1837

Pvalue > α ; We fail to reject the null and conclude that the GPA does not differ.

At α = 0.01 ; the result is insignificant

A boogie board that has a regular price of $69 is on sale at a 35% discount. What is the sale price with a 7% tax?
san4es73 [151]
You take 69 * 0.35 and then take that total (24.15) so 60-24.15= 35.85 then to find the tax take 35.85*.07=2.51 so your answer is 35.85+2.51=38.36

Any answers pls?? 20 points.
KonstantinChe [14]

Answer:

\sqrt32

Step-by-step explanation:

You use the Pythagorean theorem since a triangle is formed.

a^{2} +b^{2} =c^{2}

6^{2} = 2^{2} +x^{2}

36-4 =x^{2}

x= \sqrt{32}
