A manufacture of rayon wants to compare that the yield strength of 5 11⋅ kg/ 2 mm is met or not at 5% level of significance. The manufacturer draws a sample and calculates the mean to be 8 12⋅ kg/ 2 mm and the standard derivation is known to be 2⋅0kg/ mm . 2 Carry out the statistical test appropriate for this.

To determine whether the yield strength of the rayon meets the specified criteria of 11.2 kg/2 mm at a 5% level of significance, we can conduct a one-sample t-test. The null hypothesis (H0) would be that the mean yield strength is equal to 11.2 kg/2 mm, and the alternative hypothesis (H1) would be that ____ ________ ____ _____ ____ ___ ______ _______.
