A company rents out 13 food booths and 27 game booths at the county fair. The fee for a food booth is $50 plus $6 per day. The f

Stella [2.4K]

Answer:

2000 + 321d

Step-by-step explanation:

It is stated that there are 13 food booths and 27 game booths.

The fee for a food booth is a flat 50 dollars. There are 13 food booths. SO

13 x 50 = 650 -----> This is one part of our expression.

Next, it is 6 dollars per day per food booth, and there are 13 food booths. SO

13 x 6d =78d (Note that it says that D can be used for the number of days)

Next, we need to solve for the game booths. A game booth also has a flat fee of 50 dollars. There are 27 of them.

50 x 27 = 1350 -----> This is the second part of our equation.

Next we need to calculate the amount per day per game booth.

9d x 27 = 243d. Putting all of these together, we get ---->

1350 + 650 + 243d + 78d

Adding all these up together, we get:

2000 + 321d

A study of 10 different weight loss programs involved 500 subjects. Each of the 10 programs had 50 subjects in it. The subjects

Yakvenalex [24]

Answer:

a) (iii) ANOVA

b) The ANOVA test is more powerful than the t test when we want to compare group of means.

Step-by-step explanation:

Previous concepts

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

If we assume that we have $p=10$ groups and on each group from $j=1,\dots,p=10$ we have $n_j$ individuals on each group we can define the following formulas of variation:

$SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2$

$SS_{between}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2$

$SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2$

And we have this property

$SST=SS_{between}+SS_{within}$

Solution to the problem

Part a

(i) confidence interval

False since the confidence interval work just when we have just on parameter of interest, but for this case we have more than 1.

(ii) t-test

Can be a possibility but is not the best method since every time that we conduct a t-test we have a chance that we commit a Type I error.

(iii) ANOVA

This one is the best method when we want to compare more than 1 group of means.

(iv) Chi square

False for this case we don't want to analyze independence or goodness of fit, so this one is not the correct test.

Part b

The ANOVA test is more powerful than the t test when we want to compare group of means.

The display of a student's calculator shows: 1.2731568

8_murik_8 [283]

Answer:

rational

Step-by-step explanation: because the decimal terminates, it is necessarily rational - specifically, rational with a denominator that is a power of 10. Thus 1.3 = 13/10, 0.5761 = 5761/10000, and

1.2731568 = 12731568/10000000.
