A math teacher is investigating the problem of students losing their graphing calculators because their names aren’t written on them. In a random sample of 50 students, only 32 had their names written on their graphing calculators. The teacher constructs a 99% confidence interval for the proportion of all students at this school who have their names written on their graphing calculators and obtains (0.465, 0.815). What is the correct interpretation of this confidence interval? The teacher can be 99% confident that a majority of students at this school write their names on their graphing calculators. The teacher can be 99% confident that the interval from 46.5% to 81.5% captures the true proportion of students who write their names on their graphing calculators. In 99% of samples taken, between 46.5% and 81.5% of the sampled students would write their names on their graphing calculators. There is a 1% probability that the proportion of all students who write their names on their graphing calculators is either below 0.465 or above 0.815.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
