Answer:
y=5
Step-by-step explanation:
We are solving
The logarithm is basically asking us this question:
Or what power should I raise 2 to so that it will give me 32?
We know that
Therefore .
<em>P.S: calculating logarithms is not an algorithmic process: you have to rely mostly on educated guesses to get your answers.</em>
Answer:
Now we can calculate the degrees of freedom for the statistic given by:
And we can calculate the p value given by:
Since the p value is very low we have enough evidence to reject the null hypothesis and we can conclude that the players' birthdates are not uniformly distributed throughout the year
Step-by-step explanation:
We need to conduct a chi square test in order to check the following hypothesis:
H0: There is no difference of birthdates distributed throughout the year
H1: There is a difference between birthdates distributed throughout the year
The level of significance assumed for this case is
The statistic to check the hypothesis is given by:
The table given represent the observed values, we just need to calculate the expected values with the following formula
And replacing we got:
And now we can calculate the statistic:
Now we can calculate the degrees of freedom for the statistic given by:
And we can calculate the p value given by:
Since the p value is very low we have enough evidence to reject the null hypothesis and we can conclude that the players' birthdates are not uniformly distributed throughout the year
