A study was conducted at California State University at Chico that compared the texting speed of right-handers and left-handers. The 64 right-handers tested had a mean texting speed of 181.25 characters per minute with a standard deviation of 17.33 characters per minute. The 31 left-handers tested had a mean texting speed of 184.74 characters per minute with a standard deviation of 16.46 characters per minute.

Do the results of this study provide sufficient sample evidence to indicate that there is a significant difference in the mean texting speed of right-handers and left-handers?

Can you please use the T-84 CALCULATOR. Thank you!!
