Stats

I have tried to find the p value and z statitcs for each of the firms below and I am so confused becuase my answers arent making any sense. The randome sample is 40, the hypothesis we are testing is a lower tail test 35, pop st deviation is 6 and level of sig is 0.03. I have tried to find the p values but it doesnt make sense because my answers look wrong because for firm 1 the p value i got was 0.99 and the z stat. was 2.65 and for firm 2 the p value was 0.04 and the z st was -1.73. I kniw this is wrong because the values for the z score should all be negative because its a lower tail test. Please help - below is the data for the firms from excel, I honeslty need help and I want to understand how to do it
