customers. The company conducted a
survey to understand the perceptions of customers about a 100% leather shoe. The company has taken a random sample of 130

their lifestyle. Out of 150 females, 90
females responded that a 100% leather shoe matches their lifestyle. Does this indicate that there is a

population stating that a 100% leather shoe matches with their lifestyle? Test
the hypothesis by taking 95% as the confidence level.
