Researchers conducted a study to determine whether magnets are effective in treating back pain. The results compare a treatment group (with magnets) and a sham (or placebo) group. Reduction in back pain is the dependent measure. Assume independent, normally distributed populations with unequal standard deviations.### Data Summary- **Sample sizes ($n$):** 25 for each group- **Mean reduction ($\bar{x}$):** - Treatment ($\mu_1$): 0.53 - Sham ($\mu_2$): 0.46- **Standard deviations ($s$):** - Treatment: 0.93 - Sham: 1.01### Hypotheses**Option C:** $H_0: \mu_1 = \mu_2$ $H_1: \mu_1 \neq \mu_2$ **Option D:** $H_0: \mu_1 \geq \mu_2$ $H_1: \mu_1 < \mu_2$ ### Test Criteria- **Test statistic (t):** [Blank for user input, round to two decimal places]- **P-value:** [Blank for user input, round to three decimal places]### ConclusionUser selection is required to determine if the null hypothesis is rejected. Assess whether there is sufficient evidence to claim that the treatment group shows a greater mean reduction.### Argument ValidityTo evaluate effectiveness at larger sample sizes, compare means:- If the mean for the treatment group is [blank for input], assess the validity of the larger sample argument.### Confidence IntervalFormulate an interval to test the hypothesis:\[ < \mu_1 - \mu_2 < \] $ ( \text{Blank for user input}, \text{round to three decimal places} )$Please ensure you complete your answers and calculations as required.

A researcher takes sample temperatures in Fahrenheit of 17 days from New York City and 18 days from Phoenix. Test the claim that the mean temperature in New York City is different from the mean temperature in Phoenix. Use a significance level of α=0.05. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data.
