Page 2 of 21 8. Selling Cars: You sell a brand of automobile tire that has a life expectancy that is normally distributed with a mean life of 30,000 miles and a standard deviation of 2500 miles. You want to give a guarantee for free replacement tires if the tires wear out too soon, but you can only afford to give free replacements on approximately 5% of the tires you sell. How should you word your free replacement guarantee? Draw, shade and label a normal curve to illustrate your results.
A group of adult males has foot lengths with a mean of 28.43 cm and a standard deviation of 1.13 cm. Use the range rule of thumb for identifying significant values to identify the limits separating values that are significantly 25.7 cm significantly low or significantly high? Explain. Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.) Select the correct choice below and fill in the answer box(es) to complete your choice. O A. The adult male foot length of 25.7 cm is significantly high because it is greater than cm (Type an integer or a decimal. Do not round.) O B. The adult male foot length of 25.7 cm is not significant because it is between (Type integers or decimals. Do not round.) cm and O C. The adult male foot length of 25.7 cm is significantly low because it is less than cm (Type an integer or a decimal. Do not round.) cm C or significantly high. Is the…
