Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage).H0:pH0:p H1:pH1:p Use the following codes to enter the following symbols: ≥ enter >= ≤ enter <= ≠ enter !=A business knows that 30% of its customers are less than 25 years old. The business wants to increase this percentage, so they create a marketing campaign that targets this age group. They plan on taking a sample of customers after the marketing campaign is complete to test if the proportion of customers in that age group has significantly increased. Let p represent the proportion of this business's customers who are less than 25 years old after the marketing campaign. Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer: Ho: p# 0.3 H:p= 0.3 Ho :p = 0.3 H:p#0.3 Ho: p = 0.3 H:p< 0.3Let S be a sample space with 16 possible events.
