In an advertising campaign, a snack company claimed that every 18-ounce bag of its cookies contained at least 1000 chocolate chips. Two statisticians attempted to verify the claim. The accompa data represent the number of chips in an 18-ounce bag of the company's cookies based on their study Complete parts (a) through (e) Click here to view the chocolate chip data table Click here to view the standard normal distribution table (page 1).

According to the Carnegie unit system, the recommended number of hours students should study per unit is 2.  Are statistics students' study hours less than the recommended number of hours per unit? The data show the results of a survey of 13 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 0.7, 1.8, 1, 0.6, 3, 0.9, 0.9, 1, 3.2, 1.5, 0.1, 0.1, 3.2 What can be concluded at the αα = 0.10 level of significance?    The test statistic     =  ___________ (please show your answer to 3 decimal places.) The p-value =  ____________ (Please show your answer to 4 decimal places.)

Patients with two kinds of diagnoses were randomly assigned to one of three types of therapy and the effectiveness of the therapy was measure a 1-to-15 scale (with a higher number indicating greater effectiveness).

According to the Carnegie unit system, the recommended number of hours students should study per unit is 2.  Are statistics students' study hours more than the recommended number of hours per unit? The data show the results of a survey of 11 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 2, 2.9, 4.5, 0.7, 3.3, 4.5, 4.2, 1.2, 0.9, 1.8, 2.8 What can be concluded at the αα = 0.05 level of significance?  The p-value =  (Please show your answer to 4 decimal places. Based on this, we should Select an answer fail to reject accept reject  the null hypothesis Thus, the final conclusion is that ... The data suggest the populaton mean is significantly more than 2 at αα = 0.05, so there is enough evidence to conclude that the population mean study time per unit for statistics students is more than 2. The data suggest the population mean is not significantly more than 2 at αα = 0.05, so there is enough evidence to…
