**Analyzing the Number of Downloaded Apps in Major U.S. Cities**A researcher aims to analyze the number of apps downloaded by people on their phones across different major cities in the United States. Below is the data collected from four key cities:- **San Francisco**: 48, 37, 57, 42, 31, 44, 45, 53, 58, 41- **Los Angeles**: 25, 32, 30, 25, 50, 37, 25, 42, 30, 33- **Chicago**: 14, 35, 29, 25, 23, 27, 40, 20, 32, 55- **New York**: 30, 22, 40, 50, 30, 45, 32, 35, 42, 20**Research Question:**Can we determine if there is a significant difference in the number of apps downloaded by people across these cities? (Assume a significance level of α = 0.10)**Hypothesis Testing:**- **Type of Test:** [Specify the test used, e.g., ANOVA, t-test, etc.]- **Null Hypothesis:** [Formulate the null hypothesis, usually stating that there is no significant difference in the number of apps downloaded across the cities.]- **Alternate Hypothesis:** [Formulate the alternative hypothesis, typically indicating that there is a significant difference.]- **SE (Standard Error):** [Provide the standard error used in the calculations, if applicable.]- **Test Statistic:** [Specify the calculated test statistic value.]- **P-value:** [Include the p-value indicating the probability of observing the test results under the null hypothesis.]- **Decision:** [State whether to reject or not reject the null hypothesis based on the p-value and significance level.]**Conclusion:**- **Sentence:** [Conclude whether there is a significant difference in the number of downloaded apps among the people in these cities, based on the hypothesis test results.]By conducting this analysis, we can gain insights into the variations in app usage patterns among residents in different urban areas.
