A market analyst from a Brisbane-based business newspaper claimed that more than three quarters of customers spent more than $50 during a visit to the supermarket in the last month. 1 . State the direction of the alternative hypothesis used to test the claim. Type gt (greater than), ge (greater than or equal to), It (less than), le (less than or equal to) or ne (not equal to) as appropriate in the box. Meanwhile, another newspaper analyst, who did not originally believe the claim, took a random sample of 84 people in Brisbane to test the validity of the claim. He found that 78 of them had indeed spent more than $50 during a supermarket visit in the last month. 2. Use the required statistical table to determine the critical value of the test statistic using a 4% level of signicance. If there are two critical values, state only the positive value, correct to two decimal places. 3. Calculate the test statistic, correct to two decimal places. 4. Is the null hypothesis rejected for this test? Type yes or no. 5. Regardless ofyour answer for 4, if the null hypothesis was rejected, could we conclude that more than three quarters of customers spent more than 550 during a visit to the supermarket in the last month at the 4% level of signicance? Type yes or no
