An economist read a report that claimed that 60% of residents in her large city owned their homes. Shewondered if that figure was still accurate, so she took a random sample of n = 50 residents in the city andobserved that p = 70% of those sampled owned their homes.To see how likely a sample like this was to happen by random chance alone, the economist performed asimulation. She simulated 100 samples of n =50 residents from a large population where 60% of the residentsowned their homes. She recorded the proportion of residents who owned their homes in each sample. Here arethe sample proportions from her 100 samples:0.400.500.600.700.80Check again She wants to test Ho : p = 60% vs. Ha :p+ 60% where p is the true proportion of residents in this city thatown their homes.Based on these simulated results, what is the approximate p-value of the test?Note: The sample result was p = 70%.Choose 1 answer:Ap-value 0.05Bp-value 0.08C.p-value 0.14p-value 0.21D.

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

An economist read a report that claimed that 60% of residents in her large city owned their homes. She
wondered if that figure was still accurate, so she took a random sample of n = 50 residents in the city and
observed that p = 70% of those sampled owned their homes.
To see how likely a sample like this was to happen by random chance alone, the economist performed a
simulation. She simulated 100 samples of n =
50 residents from a large population where 60% of the residents
owned their homes. She recorded the proportion of residents who owned their homes in each sample. Here are
the sample proportions from her 100 samples:
0.40
0.50
0.60
0.70
0.80
Check again

She wants to test Ho : p = 60% vs. Ha :p+ 60% where p is the true proportion of residents in this city that
own their homes.
Based on these simulated results, what is the approximate p-value of the test?
Note: The sample result was p = 70%.
Choose 1 answer:
A
p-value 0.05
B
p-value 0.08
C.
p-value 0.14
p-value 0.21
D.
