Question

(a). A simple random sample of 37 days was selected. For these 37 days, Parsnip was fed seeds on 22 days and Parsnip was fed pellets on the other 15 days. The goal is to calculate a 99% confidence interval for the proportion of all days in which Parsnip was fed seeds, and to do so there are two assumptions. The first is that there is a simple random sample, which is satisfied. What is the second assumption, and specific to the information in this problem, is it satisfied? Explain why or why not.

(b). If appropriate, use the data in part (a) to calculate and interpret a 99% confidence interval for the proportion of all days in his life that Parsnip has been fed seeds.

(a). A simple random sample of 37 days was selected. For these
37 days, Parsnip was fed seeds on 22 days and Parsnip was fed
pellets on the other 15 days. The goal is to calculate a 99%
confidence interval for the proportion of all days in which Parsnip
was fed seeds, and to do so there are two assumptions. The first is
that there is a simple random sample, which is satisfied. What is
the second assumption, and specific...

The goal is to estimate the proportion of all days in which
Parsnip was fed seeds (as opposed to pellets) using a 99%
confidence interval with margin of error no larger than 0.22. What
is the minimum number of days that would need to be selected to
allow the calculation of a 99% confidence interval with margin of
error no larger than 0.22? It can be assumed for this problem only
that the proportion of all days in which Parsnip...

1. Of interest is to study the relationship between the number
of seeds or pellets that Parsnip eats and the amount of time that
it takes Parsnip to eat his food. A simple random sample of 37 days
is selected and each day the number of seeds or pellets eaten and
the amount of time that it takes Parsnip to eat his food is
determined. Which of the following is a graphical method that would
allow one to describe the...

(a). The population is still all days that Parsnip has been
alive, and the parameter of interest is = the proportion
of all days in which Parsnip eats all the food he is given. It is
conjectured that the proportion of all days that he has been alive
that Parsnip eats all the food he is given is 0.75, and of interest
is to test this claim versus the alternative that the proportion of
all days in which Parsnip eats all...

a simple random sample of 5000 students were selected
and asked how likely to for them to maintain a 6 feet distamce in
the classrooms if they return to campus. among the sample 5000 ,
76% of the students responded that they are somewhat or very likely
to keep the physical distance in classrooms

the true proportion of students who would be (somewhat or very
likely to...

In a simple random sample of 500 freshman students, 276 of them
live on campus. You want to claim that majority of college freshman
students in US live on campus.
A) Are the assumptions for making a 95% confidence interval for
the true proportion of all college freshman students in the United
States who live on campus satisfied? yes/no?
B) What is the sample proportion?
C.) A 95% confidence interval for the actual proportion of
college freshman students in the...

A simple random sample of 1,000 elements generates a sample
proportion p=0.55 .
a. Provide the 99% confidence interval for the population
proportion (to 4 decimals).
b. Provide the 95% confidence interval for the population
proportion (to 4 decimals).
