Answer:
the confidence interval is 90 % 0.05 < p < 0.75
and margin of error is 35 %
Step-by-step explanation:
Since 9 out of 10 students is 90 % so the confidence interval is 90 %
Range of Confidence Interval = 2* ME where ME = Margin of Error
0.75 - 0.05 = 2* ME
0.7 = 2 * ME
0.7 / 2 = ME
0.35 = ME or
ME = 35 %
One quarter of 24 is 6. Because quarter means 4. So divide 24 by4 and you get 6
1. - 7/3 2. -2 5/8 3. -2.9
Step-by-step explanation:
Any value of x must be less than -5 for n to be negative. (x<-5)
