m Problem1: The demand for roses was estimated using quarterly figures for the period 1971 (3rd quarter) to 1975 (2nd quarter). Two models were estimated and the following results were obtained: Y = Quantity of roses sold (dozens) X2 = Average wholesale price of roses ($ per dozen) X3 = Average wholesale price of carnations ($ per dozen) X4 = Average weekly family disposable income ($ per week) X5 = Time (1971.3 = 1 and 1975.2 = 16) ln = natural logarithm The standard errors

Introduction The purpose of this report is to show if the new golf ball coating design does induced resist cuts and provide a more durable ball. Hypothesis µ1 is the mean driving distance of currently produced golf balls µ2 is the mean driving distance of newly designed golf balls Null hypothesis (H0): µ1- µ2 ≤ 0 Alternate hypothesis (Ha): µ1- µ2 > 0 Analysis The sample mean for current golf balls is 270.275‚ while the new golf balls have a sample mean of 267.50. So on average the current
