7. A paint manufacturer claims that the average drying time for its new latex paint is 2 hours. To test this claim, the drying times are obtained for 20 randomly selected cans of paint. Here are the drying times, in minutes. 123 109 115 121 130 127 106 120 116 136 131 128 139 110 133 122 133 119 135 109 A researcher is interested in determining whether the data provide sufficient evidence to conclude that the true mean drying time is greater than the manufacturer's stated claim of 120 minutes.The test will be performed using a 5% level of significance. Assume that the population of drying times is approximately a normal distribution
