Based on historical data, your manager believes that 31% of the company's orders come from first-time customers. A random sample of 103 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is less than 0.32?

Answer = (Enter your answer as a number accurate to 4 decimal places.)

Answer 1

Sol: Given data fp= 31.1 p= 0.31 31 100 0.31 n= No. of Orders 103 (M) - Standard Error PCI-P) n 0:31(1-0-31) 163 0:31 X0.69 103 0.2139 103 0.045

Probability that Sample proportion is less than 0-32 P(x<0-32) - Pil X-uefp Z 0.32 - 0.31 P 1Z< 0.045 0.01 Plz 7 < 0-045 plz < 0.2222] (let - tailed) P-value from z- Score Calculator: 0.5819 (Round to 4 decimals) please Rate my work. Thank you for your continous Support to Subject Experts, stay Safe
