Final answer:
The p-value of 0.000 is less than the significance level, indicating that there is significant evidence to reject the null hypothesis and support the claim that the population mean is less than 98.6.
Explanation:
In this problem, the null hypothesis H0: Mu=98.6 assumes that the population mean is 98.6. The alternative hypothesis HA: Mu<98.6 suggests that the population mean is less than 98.6. A t-test was conducted with sample statistics: sample mean=98.3, sample std. dev=1.1, and sample size=225. The computed test statistic t0= 4.09 and the P-value is equal to 0.000.
As the P-value is less than the significance level (typically 0.05), we reject the null hypothesis. This means we have significant evidence to support the claim that the population mean is less than 98.6.
