A researcher developing scanners to search for hidden weapons at airports has that a new scanner is significantly better than the current scanner. He made his decision based on a test using Would he have made the same decision at How about Explain.

The test statistic will also be smaller α= 0.20 as α= 0.20 > α= 0.025 and the decision will be the same.

Explanation:

As when the default position has always been substantially the very same, in other words, this same innovative scanner, as well as the contemporary scanner, were also substantially similar, as well as the alternative explanation would not be considered the very same. This same conclusion was always that the latest scanner wasn't substantially superior to the current scanning machine, which means that perhaps the null hypothesis would be accepted, i.e. the confidence interval is shorter unlike "α=0.025" and therefore the alternative hypothesis would be turned down.
