A researcher believes that donations to charity decline during times of economic hardship despite the heightened need. The researcher compares results from her sample to known population data about donations. There are 800 respondents in the sample with a sample mean of $1250 in donations and a sample standard deviation (s) of $500. The population mean (μ) is $1275 in donations with a population standard deviation (σ) of $450. (All dollar values are adjusted for inflation.) If the researcher uses α = .05, does the sample data provide support for the researcher’s hypothesis? Remember to i
