Answer

See below.

Work Step by Step

If $P\lt\alpha$, then the null hypothesis is rejected. $0.013\lt0.05$, here we reject the null hypothesis. $0.74\lt0.05$, here we fail to reject the null hypothesis. Hence in case of $P=0.013$ there is evidence that there is increase and in case of $P=0.74$ there is no evidence that there is increase.
