Final answer:
The subject of this question is Mathematics, specifically statistics and probability. To determine if Accrotime watches have an average life of 32 months, a hypothesis test can be conducted. The null hypothesis assumes the average life is 32 months and a decision is made based on the sample data and statistical analysis.
Step-by-step explanation:
The subject of this question is Mathematics, specifically statistics and probability.
To determine if Accrotime watches have an average life of 32 months, we can conduct a hypothesis test. Let's assume the null hypothesis (H0) is that the average life of the watches is indeed 32 months.
A decision to reject or fail to reject the null hypothesis will depend on the sample data and its statistical analysis. If the p-value is less than the significance level (typically 0.05), we reject the null hypothesis and conclude that the watches do not have an average life of 32 months. Otherwise, we fail to reject the null hypothesis and conclude that the watches do have an average life of 32 months.
