The Valley Wine Company produces two kinds of wine—Valley Nectar and Valley Red. The wines are produced from 64 tons of grapes the company has acquired this season. A 1000-gallon batch of Nectar requires 4 tons of grapes and a batch of Red requires 8 tons. However, production is limited by the availability of only 50 cubic yards of storage space for aging and 120 hours of processing time. A batch of each type of wine requires 5 cubic yards of storage space. The processing time for a batch of Nectar is 15 hours and the processing time for a batch of Red is 8 hours. Demand for the two types of wine is limited to 7 batches, each. The profit for a batch of Nectar is $9,000 and the profit for a batch of red is $12,000. The company wants to determine the number of 1,000--gallon batches of Nectar and Red to produce in order to maximize profit.

a. Formulate a linear programming model for this problem.

Part 2: t-Procedures

In this part, we will use t-procedures. t-procedures are both confidence intervals and hypothesis tests that

use a t distribution. They are called t-procedures because they rely on a t-test statistic and/or a t-critical

value, so we only need to know the results of a sample in order to perform these procedures for a population

mean.

In Part 2, you will use the data file TempSample00-18.

This includes an SRS of daily temperature highs from January and February from the years 2000-2018

(i.e. "recent" highs). The distribution of "recent" daily high temperatures is approximately Normal.

2.1 Getting Started

2.1.1 Understanding the Set-Up

1) Describe the intended population?

2) Describe the sample?

3) Describe the variable of interest?

4) Describe the parameter of interest (in context)?

5) Describe the statistic of interest (in context)? Give a numerical value along with your description.

Round to two decimal places.

2.1.2 Checking Conditions

1) Check that the conditions for using t-procedures are satisfied. If they are not, discuss whether or not it is reasonable to use t-procedures.

2.2 Confidence Intervals

2.2.1 Motivating Question: Confidence Intervals

In 2.2, we will try to answer the question:

What is the average daily temperature high in Portland, OR for the

months of January and February during 2000-2018?

2.2.2 Confidence Interval

1) What degrees of freedom are needed?

2) What critical value is used to compute a 95% confidence interval?

In 2.3, we will try to answer the question:

Is there evidence to suggest that the average daily temperature high in Portland,

OR for the months of January and February during 2000-2018 is different than

the historical average of 48.35◦F?

years compared to "historical" years?

The authors of the paper "Age and Violent Content Labels Make Video Games Forbidden Fruits for Youth" carried out an experiment to determine if restrictive labels on video games actually increased the attractiveness of the game for young game players.† Participants read a description of a new video game and were asked how much they wanted to play the game. The description also included an age rating. Some participants read the description with an age restrictive label of 7+, indicating that the game was not appropriate for children under the age of 7. Others read the same description, but with an age restrictive label of 12+, 16+, or 18+.

The data below for 12- to 13-year-old boys are fictitious, but are consistent with summary statistics given in the paper. (The sample sizes in the actual experiment were larger.) For purposes of this exercise, you can assume that the boys were assigned at random to one of the four age label treatments (7+, 12+, 16+, and 18+). Data shown are the boys' ratings of how much they wanted to play the game on a scale of 1 to 10.

Do the data provide convincing evidence that the mean rating associated with the game description by 12- to 13-year-old boys is not the same for all four restrictive rating labels? Test the appropriate hypotheses using a significance level of 0.05.

A. Calculate the test statistic. (Round your answer to two decimal places.)   F =

B. What can be said about the P-value for this test?

P-value > 0.1000
.050 < P-value < 0.100   
0.010 < P-value < 0.0500
.001 < P-value < 0.010
P-value < 0.001

C.
Reject H₀. The data do not provide convincing evidence that the mean rating associated with the game description by 12- to 13-year-old boys is not the same for all four restrictive rating labels.
Reject H₀. The data provide convincing evidence that the mean rating associated with the game description by 12- to 13-year-old boys is not the same for all four restrictive rating labels.    
Fail to reject H₀. The data do not provide convincing evidence that the mean rating associated with the game description by 12- to 13-year-old boys is not the same for all four restrictive rating labels.
Fail to reject H₀. The data provide convincing evidence that the mean rating associated with the game description by 12- to 13-year-old boys is not the same for all four restrictive rating labels.
