To find the margin of error, multiply the z-score by the standard deviation, then divide by the square root of the sample size.The z*-score for a 90% confidence level is 1.645.The margin of error is 0.20.The confidence interval is 48.3 to 48.7.48.8 is not within the confidence interval.
Answer:
p = -2
Step-by-step explanation:
15 = -4p + 7

4p = -8
4p/4 = -8/4
p = -2
