Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation. Use a significance level of 0.05.
r = 0.75, n = 9
Critical values: r = ±0.666, no significant linear correlation
Critical values: r = 0.666, no significant linear correlation
Critical values: r = -0.666, no significant linear correlation
Critical values: r = ±0.666, significant linear correlation

An anti-smoking group used data in the table to relate the carbon monoxide of various brands of cigarettes to their tar and nicotine content.
CO = 1.37 - 5.53TAR + 1.33NIC; Yes, because the R2 is high
CO = 1.37 + 5.50TAR - 1.38NIC; Yes, because the P-value is high
CO = 1.3 + 5.5TAR - 1.3NIC; Yes, because the adjusted R2 is high
CO = 1.25 + 1.55TAR - 5.79NIC; Yes, because the P-value is too low
