Final answer:
The reference information does not provide data on January rainfall in San Jose city. It deals with rainfall data patterns and requires specific tables to find percentages and fractions of rainfall in towns, as well as projections regarding changes in rainfall related to climate change. Hypothesis testing may be relevant for analyzing rainfall differences.
Step-by-step explanation:
The amount of rainfall in January for San Jose city specifically is not provided in the reference information. However, data on rainfall patterns for a variety of scenarios is presented:
- For the number of towns with rainfall between 2.95 and 9.01 inches - you would refer to 'Table 1.16' to determine this figure, but the table is not provided in the context of our discussion.
- The fraction of towns receiving between 11.03 and 13.05 inches of rainfall annually is also noted in 'Table 1.16', but once again, specific data from the table is required to answer.
- The information on mean summer rainfall in the northeastern United States indicates that statistical methods like hypothesis testing might be employed to determine if the actual rainfall differs significantly from the mean.
- The percentage of rainfall that falls between 6.99 and 13.05 inches is yet another figure that would be found in 'Table 1.16'.
Moreover, projections for future rainfall trends due to climate change are noted, indicating a likelihood of decreased rainfall and resulting challenges for water supply in various global cities. Nonetheless, without the specific data from the mentioned tables, precise amounts cannot be provided.
