Let x be a random variable representing dividend yield of bank stocks. We may assume that x has a normal distribution withs=2.6%.A random sample of10 bankstocks gave the following yields (in percents).

• 5.7
• 4.8
• 6.0
• 4.9
• 4.0
• 3.4
• 6.5
• 7.1
• 5.3
• 6.1

The sample mean is= 5.38%. Suppose that for the entire stock market, the mean dividend yield isµ=4.9%.Do these data indicate that the dividend yield of all baCompute thezvalue of the sample test statistic. (Enter a number. Round your answer to two decimal places.)
