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

If number of cars recorded by Lynn is 1, 1, 2, 2, 2, and 4 cars then the mean absolute deviation of the number of cars is 0.7
<h3>What is the mean absolute deviation?</h3>The mean absolute deviation of a data set is the average of the absolute deviations from a central point .
Data we have is
1,1,2,2,2,4
Mean can be calculated as
Absolute value between the data points and mean can be calculated as :
Now mean absolute deviation can be calculated as :
Rounding to nearest ten
mean absolute deviation=0.7
