Defatted blackcurrant seeds (DBS) could be used as a dietary supplement in gluten-free bread but their use may affect texture. A 2011 study measured bread volume (in cm) using independent random samples of bread loaves baked with flours containing different DBS levels. The data showed no skew or outliers. Here are the summary statistics: Flour type z Mean StDev No DBS 00 552 18 5% DBS 00 525 23 15% DBS 00 485 24 We want to know if bread volume is significantly affected by the type of flour used.
Which inference procedure should be used?
1. chi-square for two-way tables
2. one sample or matched-pairs t procedure for a mean
3. z procedure for a proportion
4. two sample t procedure for two means
5. ANOVA for several means

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
