Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000 . To investigate such claims, one study used a special device to record the conversations of male and female university students over a four‑day period. From these recordings, the daily word count of the 2020 men in the study was determined. The table contains their daily word counts.

(a) Use the software of your choice to make a histogram of the data. What value should we remove from the data to make it reasonable to use the t procedures (assume these men are an SRS of all male students at this university)?

value to remove:

(b) With this value removed, carry out a test of significance to determine if the mean number of words per day of men at this university differs from 7000. (If you're using CrunchIt for your calculations, adjust the default precision under Preferences as necessary. See the instructional video on how to adjust precision settings.)

Choose the correct hypotheses to test.

H0:μ=7000 versus H0:μ>7000

H0:μ≠7000H0 versus H0:μ=7000H0

H0:μ<7000H0 versus H0:μ≠7000H0

H0:μ=7000H0 versus H0:μ≠7000H0

With the value removed, find ¯x . (Enter your answer rounded to two decimal places.)

x¯=

With the value removed, find s . (Enter your answer rounded to three decimal places.)

With the value removed, find t . (Enter your answer rounded to three decimal places.)

Using the software of your choice, find the P‑value. (Enter your answer rounded to four decimal places.)

What conclusion can we make from this data? Choose the correct answer.

A.There is no evidence that the mean number of words per day of men at this university differs from 7000 The sample mean indicates they speak less than 7000 words per day.

B.There is overwhelming evidence that the mean number of words per day of men at this university differs from 7000The sample mean indicates they speak more than 7000 words per day.

C.There is overwhelming evidence that the mean number of words per day of men at this university differs from 7000The sample mean indicates they speak less than 7000 words per day.

D.There is no evidence that the mean number of words per day of men at this university differs from 7000The sample mean indicates they speak more than 7000 words per day.

3.   [Financial Statements and Ratios] Bike-With-Us Corporation, a specialty bicycle parts replacement venture, was started last year by two former professional bicycle riders who had substantial competitive racing experience including competing in the Tour de France. The two entrepreneurs borrowed $50,000 from members of their families and each put up $30,000 in equity capital. Retail space was rented and $60,000 was spent for fixtures and store equipment. Following are the abbreviated income statement and balance sheet information for the Bike-With-Us Corporation after one complete year of operation.

Approximately 300 million golf balls were lost in the U.S. in 2009. Assume that the number of golf balls lost in an 18-hole round is distributed as a Poisson random variable with a mean of 3 balls. What is the probability that:

0 balls will be lost in an 18-hole round?

An individual can play an 18-hole round with a single sleeve of golf balls (3 balls)? (Hint: can you continue to play if you have lost all 3 balls?)

An individual who is going to play 3 rounds of golf on a trip can play all three rounds with the single sleeve of balls?

For each question please state your null and alternative hypothesis, your p-value and conclusion of your hypothesis test. You may use your calculator to perform the hypothesis.

1. Research conducted a few years ago showed that 35% of UCLA students had travelled outside the US. UCLA has recently implemented a new study abroad program and results of a new survey show that out of the 100 randomly sampled students 40 have travelled abroad. Is there significant evidence to suggest that the proportion of students at UCLA who have travelled abroad has increased after the implementation of the study abroad program? Use a .01 significance level.

   2. Sleep experts believe that sleep apnea is more likely to occur in men than in the general population. In other words, they claim the percentage of men who suffer from sleep apnea is greater than 5.8%. To test this claim, one sleep expert examines a simple random sample of 90 men and determines 9 of these men suffer from sleep apnea. Does this evidence support the claim that the percentage of men who suffer from sleep apnea not longer equals 5.8%? Use a 0.05 level of significance.

At the height of the housing crisis in the US, in 2009-2010 the Government decided for a temporary extension of unemployment benefits to 99 weeks, from the standard six months.    (In parallel way, during this Corona time, millions of unemployed seek the same kind of benefits. )

a) What do you think of this decision? What are the positive and negative impacts of this decision to the society and the overall economy?

b) How would J.M. Keynes react to this extension?

c) How would a Classical Economist say about it?

d) Along with the Unemployment Benefits, during the Corona time, as well as previous recessions, the Government poured in billions dollars to stimulate the economy through various programs (to individual taxpayers as well as small, medium, and large businesses). Some worry about the future consequence, such as Inflation. According to you, how does the increase in government spending on those programs might or might not have effect on Inflation?

Big corporations feel very evil to us now, the natural targets of blame for low-paying jobs, environmental abuse and sickening ingredients. But this thinker argued that there was an unexpected, and more important, element responsible for these ills: our taste. He encouraged the education of consumers to limit the problems of capitalism.

Select one: a. Adam Smith b. Alfred Marshall c. David Ricardo d. Karl Marx e. Thomas Malthus

This economist is one of the most influential economists and political thinkers in the history of economic thought. He started his analysis of Capitalism by starting to analyze one single "commodity". From this individual analysis of single commodities, he proceeded to investigate more complex laws and relations in Capitalism.
