He tests a random sample of 16 ofthis year’s entering students and finds that their mean IQ score is 119, with standard deviation of 15.
The college records indicate that the mean IQ score forentering students from previous years is 110. If we assume that the IQ scores of this year’s entering class are normally distributed, is there enough evidence toconclude, at the 0.05 level of significance, that the mean IQ score, J, of this year’s class is greater than that of previous years?Perform a one-tailed test. Then fill in the table below.Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)The null hypothesis:H : M = 110pSThe alternative hypothesis:H : M > 110D=0 0-0 0-0The type of test statistic:tDegrees offreedom:151=0 0-0 0-0The value of the test statistic:(Round to at least threex a ?decimal places.)The critical value at the 0.05level of significance:(Round to at least threedecimal places.)Can we conclude, using the 0.05 level ofsignificance, that the mean IQ score of this year’sclass is greater than that of previous years?YesNoSubmit Assignmento searchwNeFBF9F10& F11F12PriSoInsert%CBa56RTPGHJKVBNM<
