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.

osteoclast cells What type of organism is the cell found in? Where in the organism is the cell found? What is its function or duty? How does it contribute to the ability of the organism to maintain homeostasis? Describe the cell’s characteristics. Are there organelles? Does the cell contain components that are unique to that type of cell? Can the cell reproduce, if so, how does this occur? Is this type of cell found in other organisms?

In combinatorial transcriptional regulation, expression of a particular gene in a specific cell type is controlled by Select one: a. the combination of enhancers present in that cell type. b. the combination of transcription factors present in that cell type. c. the requirement of the gene for the cell’s function. d. the presence or absence of RNA polymerase in the cell. In eukaryotic genes, enhancer sequences are usually found Select one: a. close to the promoter region of the gene....

Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures.

Part A - Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures. In this activity, you will indicate which cell structures are found only in plant cells, only in animal cells, or in both plant and animal cells. Drag each cell structure to the appropriate bin. If a structure is found in both plant cells and animal cells, drag it to the "both"...

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.

The time that takes to complete a certain type of construction projects has a mean of 35.5 months and a standard deviation of 1.5 months. a. According to the Tchebysheff’s theorem, at least what percentage of these projects must have taken between 26.5 months and 44.5 months to complete? b. If in addition we are told that the relative frequency curve for the completion times is a bell-shaped curve, then approximately what percentage of these projects would take more than...
