Suppose you did a hypothesis test using a one-factor ANOVA that produces an F-ratio of F = 3.51. If you tested at alpha, α = 0.0

5 and the degrees of freedom for the study are df = 2, 18, what is the best decision regarding the null hypothesis?

Answer:

p_v=P(F|2,18 >3.51)= 0.0516

If we analyze the p value and the significance level given we see that p_v>\alpha so we have enough evidence to FAIL to reject the null hypothesis. So there is no evidence to conclude that at least one mean of the groups differs significantly from the others.

Step-by-step explanation:

Analysis of variance (ANOVA) is "a statistical technique that is used to check if the means of two or more groups are significantly different from each other. ANOVA checks the impact of one or more factors by comparing the means of different samples".

The null hypothesis on this case would be:

Null hypothesis: \mu_0 =\mu_1 =\mu_2

Alternative hypothesis: At least one mean is different from the other's.

We know that we have 3 groups based on the degrees of freedom for the statistic F. Since we know that F=3.51, df=2,18.

The degrees of freedom for the numerator are given by k-1=2, if we solve for k=2+1=3. And k represent the number of groups analyzed.

The degrees of freedom for the denominator are given by N-k=18, since k=3 then N=18+3=21. And that represent the number of total people analyzed.

In order to take a decision respect the null hypothesis we can calculate the p value or the critical value.

If we find the p value we got:

p_v=P(F|2,18 >3.51)= 0.0516

And if we analyze the p value and the significance level given we see that p_v>\alpha so we have enough evidence to FAIL to reject the null hypothesis. So there is no evidence to conclude that at least one mean of the groups differs significantly from the others.

The Baker Family spent $28 on 5 tickets.
White raven [17]

Answer:

I cannot not give the correct solution, need more context. How many children are there, how many adults are in the family? So I will explain in my explanation.

Step-by-step explanation:

If more context were given, for example:<em> 2 adults and 2 children.</em>

Then the bakers would have bought 2 adult tickets for ___ each

Then the bakers would have bought 3 children's tickets for ___ each

So using what we know we can create an equation:

<em>2A+3C=28</em>,<em> </em>

meaning 2 adult tickets plus 3 children's tickets costs a total of $28.

So we divide 28 by 5, which is the total amount of tickets.

28/5=5.6

So to figure the cost of children's tickets multiply the cost by amount.

3*$5.6=$16.8, C=16.8

To figure out the cost of the adults tickets multiple the cost by the amount.

2*$5.6=$11.2, A=11.2

a) the bakers would have bought <u>2</u> adult tickets for <u>5.6</u> each.

b) the bakers would have bought <u>3</u> children's tickets for <u>5.6</u> each.
