The tensile strength of silicone rubber is thought to be a function of curing temperature. A study was carried out in which 12 specimens of the rubber were prepared using curing temperatures of 20°C and 45°C. The accompanying data table shows the tensile strength values in megapascals. Compute the sample standard deviation in tensile strength for the samples separately for the two temperatures. Does it appear as if an increase in temperature influences the variability in tensile strength? Explain. Click the icon to view the data on rubber tensile strengths. The standard deviation for the low-temperature group is The standard deviation for the high-temperature group is (Round to four decimal places as needed.) Does it appear as if an increase in temperature influences the variability in tensile strength? Explain. The standard deviation for the high-temperature group is the low-temperature group. Therefore, an increase in temperature the standard deviation for variability in tensile strength.

Water Temperature If the variance of the water temperature in a lake is 26°, how many days should the researcher select to measure the temperature to estimate the true mean within 3° with 99% confidence? Round the intermediate calculations to two decimal places and round up your final answer to the next whole number. The researcher needs a sample of at least days. X Ś
