Therefore, at a 5% level of significance, the correct decision would be to fail to reject the null hypothesis. This means that there is not enough evidence to support the alternative hypothesis.

I’m considering the Epic Comp 8, likely with a 36T or 38T chainring, as I want something that can replace my Karate Monkey. While I love the Karate Monkey, I need a bike that’s faster and more efficient for these types of rides. Plus, I’m dealing with back pain, so full suspension is a must to improve comfort and reduce strain on longer rides.

To make a decision in hypothesis testing, we compare the test statistic (Z-score) to the critical value at the given level of significance.

I’m looking for a faster XC mountain bike for bikepacking, singletrack, gravel races, and ultra-distance rides of 300+ miles. Currently, my main bikes are a Lynskey GR300 and a Surly Karate Monkey, which I use as my primary bikepacking rig.

A Z-test is a statistical test used to determine whether two population means are different when the variances are known and the sample size is large. The test statistic is a Z-score (Z).

In your case, you have conducted a right-tailed Z-test and found a test statistic of Z = 0.05. A right-tailed test is a statistical test in which the area of rejection is on the right side of the sampling distribution.

The level of significance (α) is the probability of rejecting the null hypothesis when it is true. In your case, the level of significance is 5% (0.05).
