Explanation / Answer

H0:reading is normally distributed

H1:reading is not normally distributed

Given reading observations

AD=0.242

p=0.746

p>0.05

Do not reject Null hyothesis

Accept null hypothesis

Raading is normally distributed.

Solution16:

Null hypothesis,Ho:Distribution of waiting times is normally distributed

Alternative Hyothesis,H1::Distribution of waiting times is not normally distributed.

alpha=0.05

test statistic:

AD=0.874

p=0.021

p<0.05

Reject Null hypothesis.
Accept alternative hypothesis.

Conclusion:

there is no sufficient statistical evidence at 5% level of significance to conclude that distribution of waiting times is not normally distributed.

From QQ plot we conclude that times are not normally distributed as the obsevations do not fall on theoritical line.

waiting times is not normally distributed.
