Current Attempt in Progress Impact of Sample Size on Accuracy Compute the standard error for sample means from a population with mean [,1 = 110 and standard deviation 6 = 30 for sample sizes of n = 45,11 = 150,andn = 1300. Round your answers to two decimal places. Sample Size Standard Error 80f16 ( > -/4 i: If it is appropriate, give the degrees of freedom for the tdistribution and give the estimated standard error. If it is not appropriate, enter 1 in both ofthe answer elds below. Enter the exact answer for the degrees of freedom and round your answer for the standard error to two decimal places. df = standard error = 30f16 -/12 ;= ..- - -_- """'l" --- - - '9' Does the Public Support Sin Taxes? A survey of 1000 adults in the US conducted in March 2011 asked \"Do you favor or oppose 'sin taxes' on soda and junk food?\" The proportion in favor of taxing these foods was 32%.1 1\"32% favor 'sin taxes' on soda, junk food\Consider random samples of size 1200 from a population with proportion 0.65. Find the standard error of the distribution of sample proportions. Round your answer for the standard error to three decimal places. standard error = 4 of 16 - /10 E . . .
