Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). With H1: p ≠ 0.612, the test statistic is z = –3.06.

0.0011; fail to reject the null hypothesis

0.0011; reject the null hypothesis

0.0022; fail to reject the null hypothesis

0.0022; reject the null hypothesis

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
