A philanthropic organisation sent free mailing labels and greeting cards to a random sample of 100,000 potential donors on their mailing list and received 4916 donations.
(a) Give a 95% confidence interval for the true proportion of those from their entire mailing list who may donate.
(b) A staff member thinks that the true rate is 4.9%. Given the confidence interval you found, do you find that rate
plausible?
(a) What is the 95% confidence interval?
The 95% confidence interval is from 1% to %.
(Round to two decimal places as needed.)
Just question A

98 point question what is the record for most points in one

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
