You have a dataset of the average number of chirps per minute for a sample of 30 crickets. You find that the mean number of chirps per minute is 40 and that the number of chirps per minute has a standard deviation of 5 chirps. You want to test that the mean number of chirps per minute for a cricket is greater than 38 using a significance level of .05. What is the value of your test statistic? Round your answer to two decimal places.

Solution-
We have given that
Population mean = 38
Sample size = 30
Sample Mean = 40
Sample standard deviation = 5
Significance level = 0.05
Test Statistic = 2.19 ........(rounded to 2 decimals)
- Step by step test calculation
By above test result
Null hypothesis is rejected.
we have enough evidence to claim that mean number of chirps per minute for a cricket is greater than 38.

1:)
The dataset shows 15 observations of the relationship between
cricket chirps (measured in chirps per second) and outside ground
temperature (in Fahrenheit).
A. Create a scatterplot by putting chirps on the vertical axis
and temperature on the horizontal axis. Be sure to properly label
the scatterplot with a title, axes titles, and the proper units of
the variables.
B. Estimate the following relationship:
?h????=?0+?1???????????(Chirps)
̂=b_0+b_1 Temperature.
C. Interpret the slope in the context of the problem.
D. Interpret the...

The activity of a radioactive sample is the number of decays per
minute that occur in the sample. We measured this by detecting the
radiation entering the Geiger tube window. Explain why our readings
were actually only a small fraction of the actual activity. Also,
why did that not seem to matter in the determination of
Barium-137m’s half-life? Refer to either your A vs. t or your ln A
vs. t graph in your explanation.
