Q1 The chamber of commerce of a Florida Gulf Coast community advertises area residential property available at a mean cost of $75,000 per lot. You want to prove this
is wrong, specifically that the mean cost is higher than $75,000.
a. State the null hypothesis in both words and symbols.
b. State the alternative hypothesis in both words and symbols
Q2 In 2018, the Pew Research Center published a report in which it was claimed
that 44% of adults in the United States prefer watching the news on television as
opposed to reading it or listening to it on the radio. A researcher believes that
significantly more than 44% of adults prefer watching the news on television. To test
his theory, he obtains data from a random sample of 327 adults, and it is observed
that 53% of this sample prefers watching the news on television. As a first step in
conducting a statistical test of significance, the researcher will write a null
hypothesis 0. Assume that is the population proportion.
In this example, what should be the null hypothesis?
A. 0: <0.53
B. 0: >0.44
C. 0: =0.53
D. 0: =0.44
Q3 The chamber of commerce of a Florida Gulf Coast community advertises area
residential property available at a mean cost of $75,000 per lot. You want to prove this
is wrong, specifically that the mean cost is higher than $75,000. You collect a sample
of 100 residential properties and come back with a sample mean of $76,100 and a
sample standard deviation, s, of $6,481. If the null hypothesis in Q1 is true, answer the
following questions.
The center: What is the μ for your distribution?
The spread: What is the standard error for your distribution? ( s
√n)

The sample: What is the x for your sample?
Draw the distribution, with values in each blanks,
