Independent random samples were selected from two quantitative populations, with sample sizes, means, and variances given below. Population
1 2
Sample Size. 64 64
Sample Mean 3.8 5.0
Sample Variance 9.98 12.52
The value of the test statistic is
−2.02.
Calculate the p-value for a test of significant difference in the population means for the given data. (Round your answer to four decimal places.)
p-value =
Use the p-value to test for a significant difference in the population means at the 5% significance level.
- H0 is not rejected. There is insufficient evidence to indicate a difference in means.
- H0 is rejected. There is insufficient evidence to indicate a difference in means.
- H0 is rejected. There is sufficient evidence to indicate a difference in means.
- H0 is not rejected. There is sufficient evidence to indicate a difference in means.
Is this result consistent with the one obtained using the critical value approach, with = 0.05?
- Yes
- No

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o

Saline iv fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. a new supplier sells 500 ml bags for $2 each. the hospital uses about 10,000, 1000 ml bags each month. nurses report that about half of the bags are more than half full when they are discarded. if you are going to use only one supplier, which size bag provides the best deal, and how much will you save each month? compare the cost of the new supplier to the current one.
