The margarita is one of the most common tequila-based cocktails, made with tequila mixed with triple sec and lime or lemon juice, often served with salt on the glass rim. A common ratio for a margarita is 2:1:1, which includes 50% tequila, 25% triple sec, and 25% fresh lime or lemon juice. A manager at a local bar is concerned that the bartender uses incorrect proportions in more than 50% of margaritas. He secretly observes the bartender and finds that he used the correct proportions in only 10 out of 30 margaritas. Test if the manager's suspicion is justified at a= 0.05. Let prepresent incorrect population proportion. (You may find it useful to reference the appropriate table: z table or t table)

The margarita is one of the most common tequila-based cocktails, made with tequila mixed with triple sec and lime or lemon juice,
often served with salt on the glass rim. A common ratio for a margarita is 2:1:1, which includes 50% tequila, 25% triple sec, and 25%
fresh lime or lemon juice. A manager at a local bar is concerned that the bartender uses incorrect proportions in more than 50% of
margarítas. He secretly observes the bartender and finds that he used the correct proportions in only 10 out of 30 margaritas. Test if
the manager's suspicion is justified at a = 0.05. Let prepresent incorrect population proportion. (You may find it useful to reference
the appropriate table: z table or t table)
a. Select the null and the alternative hypotheses.
O Hg: p - 0.50; Ha: p+ 0.50
O Hg: p s 0.50; HA: p > 0.50
O Hg: p 2 0.50; HA: p< 0.50
b. Calculate the sample proportion. (Round your answer to 3 decimal places.)
