Answer:
The degrees of freedom are given by;
The significance level is 0.1 so then the critical value would be given by:
If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays
Step-by-step explanation:
For this case we have the following observed values:
Mon 25 Tue 22 Wed 19 Thu 18 Fri 16 Total 100
For this case the expected values for each day are assumed:
The statsitic would be given by:
Where O represent the observed values and E the expected values
The degrees of freedom are given by;
The significance level is 0.1 so then the critical value would be given by:
If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays
Answer:
x = 0
Step-by-step explanation:
-x/3 + 7 = -2x + 7
Subtract 7 from both sides.
-x/3 = -2x
Add 2x to both sides.
5/3x = 0
x = 0
2.333 is equal to the fraction 2,333/1,000 .
Answer:
We can not solve for a unique cost for each soldier.
Step-by-step explanation:
Let x be the daily cost for legionaries and y be the daily cost for archers.
Upon using our given information we will get a system of linear equations as:
Now we will solve for x from our 2nd equation,
Now we will substitute this value in our 1st equation.
We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.
Answer:
b. it neither likely nor unlikely the child will be a boy
Step-by-step explanation:
Because the probability of the child being a girl is 0.5, or half, this means the probability of it being a boy is also 0.5 or half. This means that it cannot be either likely nor unlikely
