With a ten dollar bill how much change do i get back if i buy four items, priced at 1.79, 2.99, 4.37 and 0.33
enot [183]

Add the price of the items bought and then subtract that from ten dollars:


Total bought:  1.79 + 2.99 + 4.37 + 0.33 = $9.48


Change back: 10.00 - 9.48 = 0.52


you would get $0.52 back in change.

The described situation requires inference about a mean or means. Identify the response variable and whether the setting involve
Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Hello!

The experiment was designed to proof if the physiological blind spot can be reduced with eye training.

One sample of n people was taken and the physiological blind spot was measured. After that, the people selected underwent 3 weeks of eye training and their physiological blind spot was measured again. At the end of the experiment you have two sets of data for the sample, let's call X₁: physiological blind spot of one person before taking eye training", the measurements were taken before the training will correspond to this variable, and X₂: physiological blind spot of one person after three weeks of eye training" the second measurements correspond to this variable.

In this type of situation, where only one sample is taken and both variables are measured to the same observational unit (there is a pair of observations for each person), the observations are dependant and the corresponding test is the paired samples t-test.

To analyze the information you need to create a new variable, usually symbolized as Xd, that will be the difference between X₁ and X₂.

So your response variable would be

Xd: "Difference between a physiological blind spot of one person before taking eye training and physiological blind spot of after three weeks of eye training"

Xd= X₁ - X₂

The study parameter will be the mean of the variable "difference" μd.

I hope it helps!

Jess made 3 different stacks of wooden blocks. The first stack was 8 blocks high ,the second stack was 4 blocks higher than the
kirill [66]

Answer:

Jess used 40 blocks in total.

Step-by-step explanation:

First stack: 8 blocks

Second stack: First stack + 4 = 8 + 4 = 12 blocks

Third stack: Second stack + 8 = 12 + 8 = 20 blocks

Total number of blocks: First stack + Second stack + Third stack = 8 + 12 + 20 = 40 blocks

A whAt the theoretical probability
julsineya [31]

Answer:

a.  \frac{1}{6}

b.  \frac{67}{450}

Step-by-step explanation:

Theoretical probability is what we expect to happen and experimental probability is what actually happens.

a. In theoretical probability, it doesn't matter what happened in the past. So basically we want to know the probability of rolling a 3 when a number cube is rolled.

There are 6 faces (from 1 to 6) in a number cube. And there is 1 "3". So the probabilty of rolling a 3 is:

1/6

b. In experimental probability, we need to know what happened before. When the cube was rolled 450 times, it came up "3", 67 times.

Hence the experimental probabilty of rolling a "3" is:

67/450
