Please help fast! A bacteria culture starts with three cells. Each cell in this culture doubles every hour. After t hours, the number of cells in the culture can be written as 3(2^t) Which of the following statements correctly interprets the meaning of 2^t in this context?

The factor 2^t is the number of hours.
The factor 2^t is the initial number of cells.
The factor 2^t is the number of cells in the culture after t hours.
The factor 2^t is the number of cells that each original cell in the culture has produced after t hours.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
