Question

The eruption height and the time interval after eruption of a geyser were measured and are shown below. Answer parts a-c. click here to view a table of critical values for the correlation coefficient Find the value of the linear correlation coefficient r. r = ___ (Round to three decimal places as needed.) Find the critical values of r from the table showing the critical values for the pearson correlation coefficient using alpha = 0.05. for The critical values are plusminus ___ (Round to three decimal places as needed.) is a there sufficient evidence to conclude that there is a linear correlation between the two variables? Yes, because the absolute value of the correlation coefficient is greater than the critical value. No because the absolute value of the correlation coefficient is less

Explanation / Answer

Correlation: Height x, interval after y

Pearson correlation of Height x and interval after y = 0.942

I can give rest answers using p-value approch :

p-value =0.0000

So we p-vale < 0.05 we reject null hypothesis. we conclude that there is enough evidence that there is linear relationship between two variables.
