The lifetimes of certain flies are approximately normally distributed with mean μ=1530 minutes and σ=59 minutes. What is the 6th percentile for the life expectancy of these flies? Round your answer to the nearest hundredth of a minute. 6th percentile:
Emissions of sulfur dioxide set off chemical changes in the atmosphere that result in "acid rain." The acidity of liquids is measured by pH on a scale of 0 to 14. Distilled water has pH 7.0, and lower pH values indicate acidity. Normal rain is somewhat acidic, so acid rain is sometimes defined as rainfall with a pH below 5.0. Suppose the pH of rain at one location varies among rainy days according to a Normal distribution with mean 5.30 and standard deviation 0.43. What proportion of rainy days have rainfall with pH below 5.0?
The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean u, the actual temperature of the medium, and standard deviation o. n USE SALT What would the value of o have to be to ensure that 95% of all readings are within 0.8° of µ? (Round your answer to four decimal places.) You may need to use the appropriate table in the Appendix of Tables to answer this question.

Calcium levels in people are normally distributed with a mean of 9.7 mgdL and a standard deviation of 0.5 mgdL . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
A different I/O psychologist wants to know if there is a difference in worker evaluations depending if the employee is a male or female. A group of managers were recruited and each rated both 15 men and 15 women employee evaluations on a scale of 0-10. The ratings on the worker evaluations were recorded for each manager. Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test ANOVA
