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

Answer:
0 and -3
Step-by-step explanation:
Natural numbers are all whole numbers from 1 to infinity. i.e
1, 2, 3, 4 . . .
These numbers do not include 0.
Integers are all whole numbers (positive and negative) including 0. i.e
. . ., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, . . .
These numbers are all natural numbers including their negative counterparts (i.e negatives of the natural numbers) and also 0.
<em>So from the options in the question:</em>
1 is a natural number as well as an integer
-5.41 is not a natural number neither is it an integer.
3 root 12 (written as ) is neither a natural nor an integer number.
0 is an integer but not a natural number
-3 is an integer but not a natural number
-9/7 is neither a natural nor an integer number.
23 is a natural number as well as an integer
Therefore, 0 and -3 are integers but not natural numbers
