Suppose the Proportion of Women Who Follow a Regular Exercise $\mathrm { P } _ { \mathrm { W } }$

Suppose the proportion of women who follow a regular exercise program is $\mathrm { P } _ { \mathrm { W } }$ and the proportion of men who follow a regular exercise program is $\mathrm { Pm }$ .A study found a 98% confidence interval for $p _ { W } - p _ { m }$ is $( - 0.022,0.111 )$ Does this study provide strong evidence of a gender-based difference in exercise? Explain.
