a discount to its most popular engagement ring, currently priced at $1500. The consultant wants to determine if the average amount consumers spend on similar engagement rings is more than $1500. To do this, she selects a random sample of 18 other jewelry stores in the area and records the prices of engagement rings with a similar style, cut, and weight. The prices of these rings are shown below. $1950, $1850, $1695, $1580, $2875, $1970, $1475, $1450, $1720, $1920, $1300, $1600, $1525, $1500, $1100, $1310, $1490, $1560 Using this sample data, she calculates a mean of $1659.44 and a standard deviation of $383.61 and plans to use this information to conduct a one-sample t-test of Ho: # = $1500 against H,:# > $1500. Is this an appropriate use of a one-sample t-test? No, because a one-sample f-test can only be used when the sample size is at least 30. Yes, because the data come from a random sample. No, because the sample contains an outlier. Yes, because the population standard deviation is not known. Yes, because the population is normally distributed
