We asked UST employees to tell us how many megabytes of memory (RAM) they have on their computer. We would like to test to see if the mean amount of memory is the same for three different academic departments. We have the memory amounts for six faculty members' machines in the three departments shown below. Dept. 1 Dept. 2 Dept. 3 1 2048 4096 4096 1024 2048 4096 3 1024 2048 8192 computer 4 2048 4096 8192 1024 2048 4096 2048 8192 2048 Here is the ANOVA table: Source DF Adj SS Adj MS F-Value P-Value Factor x 39263346 19631673 x.xx 0.025 ns Error Xx 61691221 4112748 Total xx 100954567 Ip After ANOVA, assume that we want to do the pairwise comparison test of the mean for department 1 to the mean for department 2. The only thing I need you to do is calculate the t test statistic.

A researcher is interested in the affects that a person’s avatar (i.e. visual representation of oneself) has on the number of profile views on Facebook.com.  The average number of individual personal profile views is known to be 230 views per day (excluding bands, artists, etc.).  The researcher creates 36 fictitious profiles that contain roughly the same information but the picture (avatar) is an animated .gif of a smiling face (36 faces randomly selected from a compilation of faces judged to be of average attractiveness).  The results showed that of the 36 profiles the average number of views was 250 with a standard deviation of 60.  Test the hypothesis that the average number of views for a smiling face gif is significantly different than the usual number of personal profile views.

The table shows the leading causes of death in a certain country in a recent year. The population of the country was 311311 million. If you lived in a typical city of​ 500,000, how many people would you expect to die of cancercancer each​ year?             Cause Deaths   Cause Deaths   Heart disease 596 comma 700596,700   ​ Alzheimer's disease 84 comma 90084,900   Cancer 575 comma 300575,300   Diabetes 73 comma 40073,400   Chronic respiratory diseases 143 comma 100143,100   ​ Pneumonia/Influenza 53 comma 40053,400   Stroke 128 comma 600128,600   Kidney disease 45 comma 30045,300   Accidents 122 comma 500122,500   Suicide 38 comma 60038,600   About people would be expected to die of cancer each year. ​(Type a whole number.

If 30 participants each completed a memory task three times — once each after having no, moderate, or high levels of caffeine, calculate the total degrees of freedom.

A researcher wants to know how long it takes, on average, for a certain species of bacteria to divide. She watches 17 cells through a microscope and times how long it takes them to divide. She obtains the following data, in hours:6.7, 10.5, 4.8, 5.2, 5.2, 10.6, 4.4, 5.7, 10.9, 7.5, 5.3, 4.4, 5.7, 5.2, 6.9, 4.5, 7.7Assuming the population standard deviation is σ=2σ=2, construct a 94% confidence interval for the average time it takes this species of bacteria to divide.xˉ=x̄=α2=α2=zα2=zα2=Margin of Error: E=E=We are 94% confident that this species of bacteria takes, on average, between  hours and  hours to divide.___

(For Questions 17-19 and 20-24). The following data was collected from a clinical trial testing a new drug aimed to lower blood pressure for individuals older than age 45. Half of the 20 participants received the new drug (Treatment = Yes) and the other half of the participants received a placebo pill (Treatment = No). Their age and gender was also recorded. Please use this data for Questions 17-19 and 20-24 and note, not all the information in the table will be used for either problem, you must decide what is relevant based on what the problem is asking.
