The equation for Direct Variation is y =kx, where k is the constant, so the constant being multiplied by x is (1/6). This means that k = (1/6).
Answer:
70.06
Step-by-step explanation:
Given the mean = 1217
Standard deviation = 51
And sample size = 80
Mean of bar x = 1217
Sd/√n
= 51/√80
= 5.7060
P(bar x<1220)
P(z < 1220-1217/5.7020)
= P(z<0.5261)
= 0.7006
Therefore the level of confidence in response to this question is 0.7006.
This statement can be made with 70.06% level of confidence.
