Answer:
It would be less than 0.05.
Step-by-step explanation:
The hypothesis test was done to claim that the weight of participants has changed.
The null and alternative hypothesis could be written as:
being μ the population mean change in weight.
With that information, we can tell that is a two tailed test. Sample means that fall in any of the tails, with a z-statistic over 1.96 or under -1.96 (at a significance level of 0.05), will be evidence to reject the null hypothesis.
The information we have about the sample is the 95% confidence interval calculated from the sample information.
This confidence interval does not include the value μ=0.
Then, there is 2.5% of probabiltity that the population mean is under 2.177, the lower bound of the interval, which includes the value μ=0.
With this information, we can conclude that the P-value have to be under 0.05.
80 times could Kaitlyn expect to pull out a blue chip.
<u>Step-by-step explanation</u>:
- The total number of chips in the bag = 7 white+5 red+ 8 blue = 20 chips.
- Probability (blue chip) = number of blue chips / total chips
P(blue) = 8/20
She does this 200 times.
P(blue) for 200 times = (8/20)200 = 80.
