A type II error fails to reject (accepts) the null hypothesis, although the alternative hypothesis is the true state of nature.It confirms an idea that should have been rejected, claiming that two observances are the same, even though they are different.n example of a type II error would be a pregnancy test that gives a negative result, even though the woman is in fact pregnant. In this example, the null hypothesis would be that the woman is not pregnant, and the alternative hypothesis is that she is pregnant.
If I could only recommend one device for streaming video today, it would be the new Roku Streaming Stick. At $50 it's one of the least expensive home video devices you can buy. It's also one of the best. Roku is the king of streaming, with more worthwhile apps than anybody else.
Probably the best known of these devices is the Roku Streaming Stick, a small, purple streaming-media player that delivers all the Roku features we've come to like. The pint-sized player, which costs $100, slips into an MHL (Mobile High-definition Link) slot on the TV, which looks like a standard HDMI input.
