An energy drink manufacturer wants to find out the effect of
different amounts of their product on the maximum anaerobic power
level for rowers. Would an experimental or observational study
design be more appropriate?
Is energy drink X better than a placebo when it comes to
concentration? To find out, two randomly divided sets of
participants (15 in each group) are given one of the two: either
drink X or the placebo. Each participant is then asked to take a
certain test; the higher the score, the better their concentration.
After the scores are recorded, it’s found that those on drink X
scored an average of 76.5 with a standard deviation of 4.9, and...
an energy drink manufacturer has developed four new drink
flavors and would like to conduct a taste test to collect data on
customers' preferences. Six people were asked to sample and rate
each flavor on a scale of 1−20. Complete parts a through c
below.

A manufacturer of steel wants to test the effect of the method
of manufacture on the tensile strength of a particular type of
steel. Four different methods have been tested and the data shown
in Table 1. (Use Minitab)
Develop the ANOVA table and test the hypothesis that methods
affect the strength of the cement. Use a = 0.05
Use the Tukey’s method with a =0.05 to make
comparisons between pairs of means.
Construct a normal probability plot of the...
Revised experiment setup ty I-v A student wants to find out how
much energy is lost by the string rubbing at the edge of the table
when the system moves by 30cm. They come up with two methods to
make this measurement: Method 1: Calculate work done on the string
by the table, Wedge=(T1−T2)xWedge=(T1−T2)x Where T1 and T2 are the
magnitude of the force measured by the top and hanging IOLabs,
respectively. x is the distance traveled by the IOLabs,...
An astronaut wants to find out his mass while in orbit, to find
out if he is staying healthy while in space. Since he can't use a
bathroom scale (why not?), he attaches himself to a spring
(k=2500 N/m), pulls himself back from the spring's equil length by
5 m, and times one oscillation to take 1 s.
a.) What is the mass of the astronaut?
________ kg
b.) Find the potential energy stored in the spring
when it is...
A producer of a new range of energy drink introduces their
product at R25 per can. After a month of sales, they introduce a
special of R 40 for two cans. A month later they sell the product
at the original introductory price. They subsequently introduce
another special after another month of R 45 for two. After a month
of sales, they re-introduce the original special of R40 for two and
this special is kept on-going for numerous months thereafter....
