The data table below contains the amounts that a sample of nine customers spent for lunch (in dollars) at a fast-food restaurant. Complete parts (a) through (d).4.17, 4.93, 5.98, 6.49, 7.41, 7.46, 8.34, 8.59, 9.76a. At the 0.01 level of significance, is there evidence that the mean amount spent for lunch is different from $6.50?State the null and alternative hypotheses:$ H_0: \mu = 6.50 $$ H_1: \mu \neq 6.50 $(Type integers or decimals. Do not include the $ symbol in your answer.)Identify the critical value(s).The critical value(s) is(are) __________.(Round to four decimal places as needed.
