I'm working on a problem for "Inferences about the difference between two population means for independent samples: sigma 1 & 2 unknown and unequal."
The final value of "test statistic t" falls in the rejection region for 95% confidence interval, but falls in the nonrejection region for 99% confidence interval.
Should I perform additional calculations before rejecting my null hypothesis?

I'm looking for a fitness watch I can use for interval training. I don't need anything fancy, but I do want something that'll vibrate in place of beeping. Can anyone recommend something? [more inside]

Stuck at a fitness plateau. Not weight loss - fat loss. I'm about 5-8% (not exactly sure; I only have inexact measurement options) below where I want to be, which is the 10% mark. Help me get to my goal or as close as possible by the summer (and stay there)! [more inside]

Shopping for a heart rate monitor which includes an interval timer
is the cheapest Timex ($78), this
is cheapest Suunto ($115) and this
is the cheapest Polar ($140). Does anyone have experience of any of these, or have other recommendations to offer? [more inside]

I'm in the (UK) market for a MiniDV camcorder. Ideally I want one with an interval rec feature so I can use it for making time lapse films. Does anyone know of a low-ish budget model that has this please?

IntervalSignalFilter: So, I have this archival recording of an interval signal
from shortwave station WSHB, Cypress Creek, SC. Is it an excerpt from any particular song? [more inside]

Recommendations on a heart rate monitor? I'm 27 and I go to the gym four to five days a week with a ratio of about 80% weight training (3-4 days) and 20% cardio (1-2 days). I'd like to do more interval training to lower my percentage body fat and many of the online resources describe this in terms of heart rate. Not knowing a thing about heart rate monitors, I thought I'd ask here. [more inside]

Can something be both "annual" and "all year?" Say, hypothetically, an on-line film festival that runs all year but is refreshed with new films annually?
