College officials want to estimate the percentage of students who carry a gun, knife, or other such weapon. A 9898% confidence interval is desired where the interval is no wider than 6 percentage points?
How many randomly selected students must be surveyed if we assume that there is no available information that could be used as an estimate of p^.
Margin of Error, E = Z*
At 98% confidence level, Z* = 2.326
There is no estimate of . Therefore, consider = 0.5
Given value of E = 6% = 0.06
0.06 = 2.326 x
= 19.383
n = 376
376 students must be surveyed.

College officials want to estimate the percentage of students who carry a gun, knife, or other such weapon. How many randomly selected students must be surveyed in order to be 98% confident that the sample percentage has a margin of error of 2 percentage points? (a) Assume that there is no available information that could be used as an estimate of ?̂ p^. n= (b) Assume that another study indicated that 7%7% of college students carry weapons. n=
Please show clear and organized work so I can follow along. 6. Concerned about campus safety, college officials want to estimate the percentage of students who carry a gun, knife, or other such weapon. How many randomly selected students must be surveyed in order to be 97% confident that the sample percentage is within 2 percentage points of the true population percentage. A previous study resulted in this confidence interval: 0.048 <p< 0.102
There is no prior information about the proportion of Americans who support the gun control in 2018. If we want to estimate 92% confidence interval for the true proportion of Americans who support the gun control in 2018 with a 0.24 margin of error, how many randomly selected Americans must be surveyed?
There is no prior information about the proportion of Americans who support gun control in 2019. If we want to estimate 93% confidence interval for the true proportion of Americans who support gun control in 2019 with a 0.18 margin of error, how many randomly selected Americans must be surveyed?
There is no prior information about the proportion of Americans who support gun control in 2019. If we want to estimate 97% confidence interval for the true proportion of Americans who support gun control in 2019 with a 0.27 margin of error, how many randomly selected Americans must be surveyed? Answer:
There is no prior information about the proportion of Americans who support the gun control in 2018. If we want to estimate 95% confidence interval for the true proportion of Americans who support the gun control in 2018 with a 0.2 margin of error, how many randomly selected Americans must be surveyed? (Round up your answer to nearest whole number)
We want to estimate the mean weekly earnings of students at a particular college with 95% confidence. How many students must be randomly selected so that the sample mean is within $1 of the population mean? Population standard deviation is known to be $10.
1. A popular claim, nicknamed "feshman fifteen," states that many college students gain weight point) in their freshman year. You are given the 95% confidence interval as 559% <P < 78 4% Correctly interpret the interval. There is a 95% chance tha the true percentage of college freshmen who gain weight is between 559% and 78 496. 95% of sample college freshmen who gain weight will fall between 55.9% and 78 4% We are confident that 95% of college freshmen,who...
Find the sample size, n, needed to estimate the percentage of adults who have consulted fortune tellers. Use a 0.04 margin of error, use a confidence level of 98% and use results from a prior poll suggesting that 11% of adults have consulted fortune tellers. A student wants to estimate the mean score of all college students for a particular exam. First use the range rule of thumb to make a rough estimate of the standard deviation of those scores....
commercial perceptions is developed, and we want to estimate the mean score for all pilots. How many randomly selected pilots must be tested if we want the sample mean to be in error by no more than 3 points, with a 98% confidence? A preliminary study suggests that the population standard deviation is 24 points. 24. A college wishes to know the proportion of American adults who speak two or more languages. The survey includes asking 565 randomly selected American...
