Researchers use a test statistic known as the p-value to discern whether the event falls below the significance level; if it does, the result is statistically significant. The p-value is a function of the means and standard deviations of the data samples.
Directions. 1  Heat oven to 400Â° F. Pierce each sweet potato several times with the tines of a fork. 2  Place the sweet potatoes on a rimmed baking sheet lined with foil. 3  Bake until tender, about 45 minutes. 4  Make a slit in the top of each sweet potato. 5  Top with 1 tablespoon of butter and season with the salt and pepper.
Use a fork to poke holes on the top of the potatoes. Preheat the oven to 350 degrees. 3. Bake the sweet potatoes. Place the sweet potatoes directly on the rack in your oven, or on a baking sheet if you prefer. Bake for about 45 minutes, or until they feel soft inside when you poke them with a fork.
