A marketing firm surveys 11 people to see how much they like a certain perspective advertisement on a 0 to 10 scale. The following were the responses of the 10 people: { 4, 3, 2, 7, 5, 6, 1, 4, 3, 9, 0}. Find the approximate 95% confidence interval for the population mean. What is the lower bound? |
Yea I'm stuck on this problem I think it uses the Central Limit Theorem to Solve it with a normal model but I'm not sure.

You are testing to see whether there is a difference between how
much people spend on food when they're out if they are alone versus
if they are with their friends. You want to collect information on
the amount of money spent per meal at a particular restaurant for
two different groups; for your first sample (represented using
number 1), your sample contains 18 meals served to individuals
sitting by themselves. For your second sample (represented using
number 2), your...

You pool together two different marketing surveys to see what
the willingness to pay for a product is. Survey one has a mean of
$20, with standard deviation of 5, and 45 people were surveyed.
Survey two has a mean of 30, with standard deviation of 10, and 50
people were surveyed. The null is no difference. The
test-statistic, when computed, is 6.06. Would you reject the
null?

A study was conducted to see how people reacted to certain
facial expressions. A sample group of n=36n=36 was randomly divided
into six groups. Each group was assigned to to view one picture of
a person making a facial expression. Each group saw a different
picture, and the different expressions were (1) Surprised (2)
Nervous (3) Scared (4) Sad (5) Excited (6) Angry. After viewing the
pictures, the subjects were asked to rank the degree of dominance
they inferred from...

1) In a survey, 11 people were asked how much they spent on
their child's last birthday gift. The results were roughly
bell-shaped with a mean of $50 and standard deviation of $14.
Construct a confidence interval at a 90% confidence level. Give
your answers to one decimal place.
2) Out of 200 people sampled, 132 had kids. Based on this,
construct a 95% confidence interval for the true population
proportion of people with kids. Give your answers as decimals,...

Kathy only receives surveys from 221 people despite expecting to
receive 300 surveys. How will this affect the width and the margin
of error of her confidence interval for a population mean? Assume
that the population standard deviation is unknown and the
population distribution is approximately normal.
