The time it takes for a particular type of biological cell to divide into two cells...

The time it takes for a particular type of biological cell to divide into two cells is believed to follow a bell- shaped distribution with a mean of 30.2 minutes. In a lab study of 22 such cells, the average time to divide was 28.2 minutes with a standard deviation of 3.5 minutes. Does the study provide sufficient evidence to conclude that the mean division time for such cells is less than 30.2 minutes? Round to 3 decimal places if necessary. You choose the confidence level and use that value to interpret your conclusion.

a) H0: ?=_____________ H1: ?___________
b) Test statistic: ____________
c) Compute the P−value=
d)State and interpret your conclusion.

The average time it takes to complete a particular sociology test is 86.5 minutes. In a recent study of 26 individuals that took it a particular test the average amount of time to complete the sociology test was 83.4 minutes. The sample standard deviation was 8.7 minutes. At the 0.10 level of significance can it be concluded that the average amount of time it takes to complete the particular sociology test is less than 86.5 minutes.

As the chromosomes of a parent cell are duplicated and distributed to the two daughter cells during cell division

Changes in DNA structure during the cell cycle As the chromosomes of a parent cell are duplicated and distributed to the two daughter cells during cell division, the structure of the chromosomes changes. Answer the three questions for each phase of the cell cycle by dragging the yes and no labels to the appropriate locations in the table. Note: Assume that by the end of the M phase, the parent cell has not yet divided to form two daughter cells.
