(to) Formulate the null hypothesish and the alternative hypothesish . p ho :M = 0 X S p h : H d to 00 (b) Determine the type of test statistic to use. Test Statistic Type |z 0=0 030 020 (c) Find the value of the test statistic: 0*0 00 (Round to three or more decimal places.) 1.4055 X 5 (d) Find the two critical values at the significance level of0. 10: (Round to three or more decimal places). 1.7613 and1.7613 (and) at the level of0. 10Can the owner conclude that the average daily sales of the two stores differ? O Yeah ONoYour answer is incorrect. - (a) The alternative hypothesis: Your answer is incorrect. - (b) The type of test statistic: Your answer is incorrect. - (c): Your answer is wrong. 0 (d): Your answer is wrong. 0 (e): Your answer is wrong. The owner of a chain of convenience stores wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such purposes making sure to record the sales of each store in the same8days, chosen randomly. She records the sales (in dollars) of each store on these days, as shown in the table below. Day 1 shop 1 988 821 393 422 262 710 546 463 shop 2 582 734 288 252 335 513 452 255 Difference _ (Store 1 _ Store 2) 406 87 105 170 73 197 94 208 Send data to calculator V Based on these data, can the owner conclude, at the significance level of0.10, that the average daily sales of the two stores differ? Answer this question by performing a hypothesis test regardingud (what isuwith a letter "d" subscript), the population mean of the difference in daily sales between the two stores. Assume that this population of differences (Store 1 minus Store 2) follows a normal distribution. Perform a twotailed test. Then complete the parts below. Carry out intermediate calculations to three or more decimal places and round your answers as indicated. (If necessary, you can refer to a list of formulas .)
