Formal hypothesis testing. I would like all of these answers if you're just gonna do one skip it please. Thank you in advance

Here is a sample of my cell phone bills: $132.14, $ 121.67, $ 111.86, $107.97, $91.32, $104.68, $97.90 We will test the claim that my mean bill is greater than $110.00 at the 0.05 significance level. 1 . State the formal claim, the null hypothesis, and the alternative hypothesis. 2. Find the sample mean and sample standard deviation (use STAT button.) 3. Is this test two-tailed or one-tailed? 4 . What is the appropriate confidence level? (Table 8 - 1 bottom of p. 360). 3. Find the appropriate CI estimate. (Show calculator syntax.)
