Answer:
- 10 mice left after 5 years
Step-by-step explanation:
<u>The function is given:</u>
- f(x) = 5719(0.28)ˣ
- f(x) is the number of mice left after x years, 5719 is initial number of mice (now) and x is the number of years from now
<u>Substitute x with 5 for 5 years and find the value of the function.</u>
- f(5) = 5719(0.28)⁵ = 10 (rounded up to the integer number)
- Multiply 5719 by 0.28 to the 5th power to get approximate number of 10
There will be 10 mice left after 5 years

Answer:
Die is not fair given that Pvalue< 0.05, hence we reject Null hypothesis
a) H0: Die = fair
b) Ha : Die ≠ fair
c) df = 5
Step-by-step explanation:
The expected frequency of every face values = 20
a) state Null hypothesis
H0: Die = fair
b) Alternate Hypothesis
Ha : Die ≠ fair
c) degree of freedom
df = ( n - 1 )
= ( 6 - 1 ) = 5
n = sample size ( number of faces a die has )
Note : After conducting hypothesis test
Pvalue ≈ 0.0026
test statistic ≈ 18.30
Hence we can conclude that die is not fair given that Pvalue < 0.05, hence we reject Null hypothesis
