The Toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (A) under a norma

Igoryamba

Answer:

Step-by-step explanation:

Given that population average is 0.8 ampere

Sample size = 9

Sample mean x bar = 1.34 A

Sample std dev s = 0.48

$H_o: x bar =0.8\\H_a: x bar >0.8$

(one tailed test)

Mean difference - $1.34-0.8 =0.54$

Std error = $\frac{s}{\sqrt{n} } =0.16$

t test can be used since sigma is not known and sample size small

t statistic = mean diff/std error = 3.5

df = 8

p value = 0.00404

Which expression is equivalent to 3n+5-6? <br> A)3n+11<br> B)8n-6<br> C)3n-1<br> D)3n+1

mixas84 [53]

3n+5-6

Just simplify it, so now you have 3n-1

Let's go through each answer.

A) 3n+11 is incorrect because it does NOT equal 3n-1

B) 8n-6 is also incorrect because it does NOT equal 3n-1

C) 3n-1 IS correct because it DOES equal 3n-1

D) 3n+1 is incorrect because it does NOT equal 3n-1

So, your answer is C) 3n-1
