With reference to Exercise 11.9, test the null hypothesis \(\beta=0.40\) against the alternative hypothesis \(\beta>\) 0.40 at the 0.05 level of significance.

Data From Exercise 11.9

11.9 Scientists searching for higher performance flexible structures created a diode with organic and inorganic layers. It has excellent mechanical bending proper- ties. Applying a bending strain to the diode actually leads to higher current density(mA/cm). Metal curva- ture molds, each having a different radius, were used to apply strain (%). For one demonstration of the phe- nomena, the data are
