Assume that a sample is used to estimate a population proportion p. Find the margin of error E (or EBP) that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. 95% confidence, n= 320, X = 60

Use the given data to find the minimum sample size required to estimate the population proportion.

a. Margin of error: 0.004; confidence level: 95%; p and q unknown.
b. Margin of error: 0,009; confidence level: 99%; P and unknown
c. Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98

The multiplicative property of equality states that for real numbers a, b, c, and d, if a = b and c = d, then ac = bd. true false
