To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil

Ugo [173]

Answer:

Step-by-step explanation:

Set up hypotheses as

$H_0: x bar = 50\\H_a: x bar$

(Left tailed test at 5% level)

Sample mean = 53.4

Sample std dev s = 4.4

Sample std error = 4.4/sqrt 50 = 0.6222

Mean diff = 3.4

Test statistic = Mean diff/std error = 0.5464

(t test only can be used as population sigma is not known)

df = 50-1 =49

p value = 0.2939

Since p>0.05 we accept null hypothesis

Given A=5x^2 and B=-3x^2+6 give the expression that represents A+B

(5x^2)+(-3x^2+6) = 2x^2+6.
