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.
When the Apple TV with the Siri remote came out, I bought that and it has been my primary streaming device for over a year. But I want to make sure Iâm not missing out on anything with other streaming devices. I bought Amazon Fire TV (Gen 2) and Roku Premiere+. Then I reset my Apple TV (Gen 4). Iâm starting fresh in my attempt to find the definitive best streaming device. Sidenote: Chromecast is a cool device, but it only works with a smartphone, and Iâm only looking at dedicated devices.
