Question: A test was conducted to determine whether gender of a display model affected the likelihood that consumers would prefer a new product. A survey of consumers at a trade show which used a female spokesperson determined that 45 of 250 customers preferred the product while 55 of 250 customers preferred the product when it was shown by a male spokesperson.

Do the samples provide sufficient evidence to indicate that the gender of the salesperson affect the likelihood of the product being favorably regarded by consumers? Evaluate with a two-tail, alpha =.05 test. Do NOT do a confidence interval.
