Asurvey of 300 union members in new york state reveals that 112 favor the republican candidate for governor. construct the 98% confidence interval for the true population proportion of all new york state union members who favor the republican candidate.

98% confidence interval for the true population proportion of all New York State union members who favor the Republican candidate is 0.373±0.065, that is between 0.308 and 0.438

Step-by-step explanation:

Confidence Interval can be calculated using p±ME where

and margin of error (ME) around the mean can be found using the formula

ME= where

Then ME=[tex]\frac{2.33*\sqrt{0.373*0.627}}{\sqrt{300} }[/tex≈0.065

98% confidence interval is 0.373±0.065

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
