HELP :) thankyou psychology for statistics

A researcher calculated a correlation between 1.Q and reaction time (secs.) in a sample of professional boxers. The results were r= .22, p =.047. This means: Select one: O a. there is a medium negative correlation between 1Q and reaction time O b. as IQ increased reaction time increased O c. The variables are not significantly correlated . d. the effect size was medium but the significance was low General practitioners were surveyeu UnTIM.. they saw each day. The 95% confidence interval around the mean of 50 was 40-60. The 99% confidence interval would therefore: Select one: O a. be 42.5-57.5 O b. be 45-55 O c. be larger than the 95% confidence interval O d. be smaller than the 95% confidence interval With an obtained t of 2.94 and a critical t value of 2.98 at a .05 we would conclude: Select one: O a. that we should accept the alternate hypothesis O b. that we should accept the null hypothesis O c. that we need the degrees of freedom to make a decision O d. that the effect size was large
