Using the expected value, it is found that the mean of the distribution equals $0.1.
The probabilities of <u>each outcome</u> are:
Thus, the mean is given by:
Thus showing that the expected value is $0.1.

Answer:
The calculated value Z = 1.183 < 1.96 at 0.05 level of significance
Null hypothesis is accepted
A particular greyhound breeder claims that her dogs are faster than the average greyhound
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given the average speed of greyhound dogs is about 18.4 meters per second.
Size of the sample 'n' = 35
mean of the sample x⁻ = 18.7
Population standard deviation = 1.5m/s
level of significance (∝) = 0.05
<u><em>Step(ii):-</em></u>
Null hypothesis : H₀ : μ = 18.4
Alternative hypothesis H₁ : μ ≠ 18.4
Test statistic
Z = 1.183
<u><em>Conclusion:</em></u>-
The calculated value Z = 1.183 < 1.96 at 0.05 level of significance
Null hypothesis is accepted
