# 0.10 Hypothesis testing of single mean and single proportion: lab

 Page 1 / 1
update of figure 1 to be a normal curve

Class Time:

Name:

## Student learning outcomes:

• The student will select the appropriate distributions to use in each case.
• The student will conduct hypothesis tests and interpret the results.

## Television survey

The data in the Testbook.mtw file lists the cost of 62 books required for classes in Summer 2008 at Mesa College. Students believe that they are spending on average \$100 for their textbooks. Using the data for new books as the sample, conduct a hypothesis test to determine if the average cost of new textbooks at Mesa is lower.

• ${H}_{o}$ :
• ${H}_{a}$ :
• In words, define the random variable. __________ =
• The distribution to use for the test is:
• Calculate the test statistic using your data.
• Draw a graph and label it appropriately.

Graph:
• ## B

Calculate the p-value:
• Do you or do you not reject the null hypothesis? Why?
• Write a clear conclusion using a complete sentence.

## Language survey

According to the 2000 Census, about 39.5% of Californians and 17.9% of all Americans speak a language other than English at home. Using your class as the sample, conduct a hypothesis test to determine if the percent of the students at your school that speak a language other than English at home is different from 39.5%.

• ${H}_{o}$ :
• ${H}_{a}$ :
• In words, define the random variable. __________ =
• The distribution to use for the test is:
• Calculate the test statistic using your data.
• Draw a graph and label it appropriately. Shade the actual level of significance.

Graph:
• ## B

Calculate the p-value:
• Do you or do you not reject the null hypothesis? Why?
• Write a clear conclusion using a complete sentence.

The deference between Monopoly and Oligopoly: Monopoly means:A single-firm-Industry producing and selling a product having no close business and Oligopoly means:A market structure where a few sellers compete with each other and each controls a significant portion of market .

the word economic was derived from the Greek word oikos (a house)and mein(to manage) which in effect meant managing a household with the limited funds available 🙂.

hon
An Enquiry into the nature and causes of wealth Nations, this book clearly defined what economic is🙂🙂🙏🙏 thank you...
Basanta
good example about scarcity: money,time, energy, human or natural resources. Scarcity of resources implies that there supply is very much limited in relation to demand.
Basanta
equilibrium is a situation in which economic forces such as demand and supply are balanced and in the absence of external influences,the value of economic variables will not change
hmnn

marginal cost and marginal revenue is equilibrium .

Abdulai
Helloo, im new, can i get to know more?
You ask questions on any topics you find difficult.

is price elasticity of demand the same as elasticity of demand
not really

price elasticity of demand is the reaction of customers /demand to price changes(increase or decrease) elasticity of demand is the reaction of prices brought about by the change in demand
Victoria
thank you
Favour
state the laws of demand and supply
William
dd: when price rises demand decreases whereas when price reduces dd rises ss: when ss rises the price rises and when ss decreases price also reduces. There is a positive relationship
Dhoonah
nice
Victoria
Draw a demand curve graph
William
though price elasticity and elasticity are used interchangeably, the demand can respond to income changes and prices of related goods as well.
Gurpalak
explain the difference between merit goods and public goods and show why it is possible for profit to be made in the supply of one of these types of good but not the other
Kavishek
Public goods are defined as products where, for any given output, consumption by additional consumers does not reduce the quantity consumed by existing consumers. Merit goods are, for example, education and to some extent the health-care. They are provided by state as "good for you".
