Amelie has a spinner divided into ninths equal sections that are labeled 1 through 9. she wants to compare the theoretical proba

bility and experimental probability as spending an odd number she spends the spinner 12 times and records the results in this list. Drag and drop the answers into the boxes to correctly complete the sentences.
•Theoretical probability of spinning in on number is equal to (blank). The probability of spinning a number is equal to (blank). Therefore the theoretical probability of being a number is (blank) the experimental probability of spelling and odd number.

Choices- 1/9. 1/2. 5/9. 2/3. greater than. less than.

HURRY PLEASE! THANK YOU GUYS

Using the probability concept, it is found that the sentence that describes this situation is given as follows:

Theoretical probability of spinning in on number is equal to 5/9. The probability of spinning a number is equal to 2/3. Therefore the theoretical probability of being a number is less than the experimental probability of spelling and odd number.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

For an experimental probability, these number of outcomes are taken from previous trials, while for a theoretical probability, they are considered before the trials.

From 1 to 9, there are 5 out of 9 odd numbers, hence the theoretical probability is given by:

pT = 5/9 = 0.5555.

Out of the 12 trials, 8 resulted in an odd number, hence the experimental probability is given by:

pE = 8/12 = 2/3 = 0.666.

Hence the sentence is:

Theoretical probability of spinning in on number is equal to 5/9. The probability of spinning a number is equal to 2/3. Therefore the theoretical probability of being a number is less than the experimental probability of spelling and odd number.

According to a survey, the average American person watches TV for 3 hours per week. To test if the amount of TV in New York City
Neporo4naja [7]

Answer:

Test statistic (t-value) of this one-mean hypothesis test is -2.422.

Step-by-step explanation:

We are given that according to a survey, the average American person watches TV for 3 hours per week. She surveys 19 New Yorkers randomly and asks them about their amount of TV each week, on average. From the data, the sample mean time is 2.5 hours per week, and the sample standard deviation (s) is 0.9 hours.

We have to test if the amount of TV in New York City is less than the national average.

Let Null Hypothesis, H_0 : \mu \leq 3  {means that the amount of TV in New York City is less than the national average}

Alternate Hypothesis, H_1 : \mu > 3   {means that the amount of TV in New York City is more than the national average}

The test statistics that will be used here is One-sample t-test statistics;

        T.S. = \frac{\bar X - \mu}{\frac{s}{\sqrt{n} } } ~ t_n_-_1

where, \bar X = sample mean time = 2.5 hours per week

             s = sample standard deviation = 0.09 hours

             n = sample size = 19

So, <u>test statistics</u> = \frac{2.5 - 3}{\frac{0.9}{\sqrt{19} } } ~ t_1_8

                              = -2.422

Therefore, the test statistic (t-value) of this one-mean hypothesis test (with σ unknown) is -2.422.

A 20 foot rope is cut so that one piece is 5 feet longer than the other. Find the length of each piece
hammer [34]

Let one piece of the rope be x

Let the other piece of rope be x + 5

These two pieces put together will make 20 feet.

So we say:

x + (x +5) = 20

What is x? We expand the equation.

x + x + 5 = 20

x + x = 20 - 5

2x = 15

x = 7.5

The shorter piece is  therefore 7.5 feet.

The longer piece is 7.5 + 5 = 12.5 feet.
