Answer:
a) Alternative hypothesis,
b) z = -2.91, Pvalue = 0.002
c)Option C. Reject H_0. There is enough evidence at the 1% level of significance to reject the claim.
Step-by-step explanation:
a) Null hypothesis,
Alternative hypothesis,
b) Standardized test statistic
Level of significance,
z = -2.91
Checking the p-value that corresponds to z = -2.906
P-value = 0.002
c) What is the proper decision
P-value = 0.002
Level of significance, α = 0.01
0.002 < 0.01
Since Pvalue < α, the null hypothesis H₀ should be rejected.
Option C is the correct option.
Answer:
8 , 7 , 6 , 5 , 4 , 3
Step-by-step explanation:
Insert your x into the equation, then simplify for y.
Answer:
y = 3
Step-by-step explanation:
2x+6y=5x+4y if x=2
2(2)+6y=5(2)+4y
4+6y=10+4y
-4 =-4
6y=6+4y
-4y= -4y
2y=6
/2=/2
y=3
