Answer:

0.29287

Step-by-step explanation:

You want to use the binomial cumulative distribution function (binomcdf). The purpose of this function is that it allows you to obtain the probability of observing less than or equal to x successes in n trials, with the probability p of success on a single trial.

x in this case is 182, n is 200, and p is 0.9005. Essentially by inputting these values, we find the probability that out of 200 passengers with a 0.9005 chance of getting on the plane, that 182 or less show up.

This gives us P(x <= 182) = 0.70713. (You need your calculator for this step, input the values above in the binomcdf function)

We want to find the probability of more than 182 passengers showing up though, so it would be 1 - 0.70713 = 0.29287.

Thus the probability that when 200 reservations are accepted for the flight, there are more passengers than seats available is 0.29287.

When utilizing ANOVA, what does the between group sum of squares measure?

zhenek [66]

Answer:

b. The sum of the squared deviations between each group mean and the mean across all groups

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"

Solution to the problem

If we assume that we have $p$ groups and on each group from $j=1,\dots,p$ 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

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

As we can see the sum of squares between represent the sum of squared deviations between each group mean and the mean across all groups.

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

So then the best option is:

b. The sum of the squared deviations between each group mean and the mean across all groups

Simplify the expression 5^8 x 5^3 Write your answer in exponent form.

djyliett [7]

Answer: 5^11

Step-by-step explanation:

If two exponents are being multiplied together, and they have the same base and different exponents then just add the exponents and let the base stay the same.

5^8 * 5^3 = 5^11
