![Listed in the data table are amounts of strontium-90 (in millibecquerels, or mBq, per gram of calcium) in a simple random sample of baby teeth obtained from residents in two cities. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use a 0.10 significance level to test the claim that the mean amount of strontium-90 from city #1 residents is greater than the mean amount from city #2 residents.

Transcribed Image Text:The table presents numerical data comparing two cities, labeled as City #1 and City #2. Each city has a list of numerical values. These could represent various measurements, such as temperature, population, sales, etc. The data is as follows:
**City #1:**
- 101
- 86
- 121
- 110
- 101
- 104
- 213
- 143
- 290
- 100
- 262
- 145
**City #2:**
- 117
- 71
- 100
- 85
- 83
- 107
- 110
- 111
- 102
- 133
- 101
- 209
This comparison could be used to analyze patterns, differences, or similarities between the two cities based on the values presented.
