What is the t* value for calculating a two-tailed 99% confidence interval for a population mean, based on a random sample of 25 observations?

What does CRI stand for? _______

In a survey conducted by the Daily Iowan newspaper,  180 out of  of 300 randomly selected UI students said they were satisfied with their living conditions.  The Daily Iowan claimed, “60% of UI students are satisfied with their living conditions, with a margin of error of plus or minus 4 percentage points, at the 95% level of confidence.”  Which of the following statements about the Daily Iowan claim is correct?

There are four categories of metadata associated with images. List all four. _______ , _______ , _______ and  _______ .

For the following exposures, enter the appropriate missing parameter to achieve the desired outcome. “N” is your base exposure. Start with the Base Exposure N for each new exposure calculation. NOTE: only enter the shutter speed, for example 1/2 sec should be entered as 1/2. A= _______ B = _______ C =  _______

Two methods of teaching statistics are to be compared.  Method A (traditional) involves lectures, textbook, and study manuals.  Method B (experimental) involves the use of computerized instruction, with each student using the computer whenever s/he pleases for as long as s/he pleases.  From the 32 students who enrolled for this course, one-half were randomly assigned to each method.  At the end of the semester, a valid achievement test was given to the students in both groups.  The results of this study will be used to help decide if Method B should be adopted in place of Method A.  The following summary statistics were obtained: Method A Method B n 16 16 Mean 50 57 SD 10 10 The researcher decided to construct a two-sided 90% confidence interval for the population mean difference.  Assuming the estimated standard error was 3.0 (actually it was not) and using the sample data provided, which of the following represents the appropriate interval?

A market researcher studied three background music conditions in a supermarket:  French accordion music, Italian string music, and no music.  Under each condition, the researcher recorded how many bottles of French, Italian, and other wine were purchased.  The table below summarizes the observed frequencies. The researcher wants to use the Chi-Square test to determine whether there is a relationship between background music and type of wine purchased. What is the expected frequency for the number of bottles of French wine purchased when Italian music was playing?  

A consumer advocate was interested in the effectiveness of Evelyn Wood’s Speed-Reading Course.  One hundred students were randomly sampled from a population of college sophomores.  Two groups of fifty students were created using random assignment.  Group A (treatment) received the course while Group B (control) was instructed to use whatever means necessary to improve reading speed and comprehension.  After the course, a reading achievement test was given to the students in each group (higher test scores indicate higher levels of speed and comprehension), and the results were as follows: Group A (Treatment) Group B (Control) n 50 50 Mean 75 80 SD 23 20 Suppose the observed P-value for testing the null hypothesis that the population mean difference is zero was 0.06 (it isn’t).  That means that
