How many months had no days with 0.5 inches or more of precipitation? What proportion of months had no days with 0.5 inches or more of precipitation? Construct a 95% confidence interval for the proportion of months that had no days with 0.5 inches or more of precipitation. Does this analysis make sense?

Now consider the variable EMXT (extreme maximum temperature). Construct a 99% confidence interval for the extreme maximum temperature for a month. Does this analysis make sense?

For your fourth journal entry, consider again the variable DP05. Last week you constructed a 95% confidence interval for the number of months that had no days with 0.5 inches or more of precipitation.

A resident thinks that 15% of the months have no days with 0.5 inches or more of precipitation. Test this claim at a 0.05 significance level. How do your results compare to your 95% confidence interval from the Module Three journal?

Now consider the variable EMNT. This is the extreme low temperature (extreme minimum temperature) for the month, also reported in tenths of a degree Celsius. For example, a value of -50 in EMNT means that the extreme low for the month was -5 degrees Celsius, or 23 degrees Fahrenheit.

A resident thinks that the extreme low temperature during a randomly chosen month is about -5 degrees Celsius. Test this claim at a 0.01 significance level. Use both the classical method and the p-value method. Does this analysis make sense?
