A supervisor of a textile industry collected information regarding the mean number of hours of productive work done by a random sample of ten workers in a month. After the performance bonus was announced by the management, the supervisor again collected the information of the mean number of hours of productive work done by the same ten workers in the next month. The results are summarized below. Worker 1 2 3 4 5 6 7 8 9 10Before bonus 6.8 6.2 74 6.9 7.1 6.56 6.5 7.56.7 After bonus 6.5 7.57 7.3 6.7 6469 7.3 6. Construct a 99% confidence interval for the difference in the mean number of hours of productive work done by the workers in the month before and after the announcement of the bonus. a. [0.04,0.34] b. [0.01, 0.37 c. [-0.22,-0.16] d. [-0.34,-0.04) e. [-0.37,-0.01]

step-by-step explanation:

1. she sold more on day 2 because if you turn .85 into a fraction{85/100} and you give 7/9 and 85/100 the same denominator{180} you can see which one has the bigger numerator and that one will be the most sold.

2. yes it is in simplest form, because if you look at 38 and 53 's greatest common factor, you cant find one so you cant reduce it

3. no, this is not a prime factorization because the numbers are not all prime numbers, the correct prime factorization is:   2 x 5 x 2

4.   in 12 days he will run and play trumpet again
