Answer: I think 100,000
Step-by-step explanation:
Answer:
Based on statistical analysis the claim is of 3% of patients developing adverse reaction is valid and there is a drug problem
Step-by-step explanation:
Here we have
Percentage of patients that develop nausea em= 153/5783 *100 = 2.65 %
To test the hypothesis, we put our null hypothesis as
H₀: μ = 3%
Alternative hypothesis is then
Hₐ: μ < 3%
Therefore the test statistic is
![t=\frac{\hat{p}-p_0}{\sqrt{\frac{ p_0( 1- p_0)}{n}}}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B%5Chat%7Bp%7D-p_0%7D%7B%5Csqrt%7B%5Cfrac%7B%20p_0%28%201-%20p_0%29%7D%7Bn%7D%7D%7D)
P₀ = 0.03
= 0.0265
n = 5783
From the above we have our test statistic as -1.579 from which gives our p value as P = 0.057.
Therefore, as we have our P value less than the confidence level of 0.05, we therefore fail to reject the null hypothesis because there is sufficient statistical evidence that suggest that the proportion of patients who would have adverse reaction to the drug = 3%.
Answer:
0
Step-by-step explanation:
everything multiplied by 0 is 0
The ratio of perimeters is sqrt49:sqrt16 = 7:4
so perimeter of second polygon = 22 * 4/7 = =88/7 = 12. 57 cm
Answer:
D
Step-by-step explanation:
So, one friend rolled a 1 and the other rolled a 3. Taylor needs to roll a number higher than both friends in order to win.
So, the possible numbers Taylor can roll to win are 4, 5, or 6.
Out of the six possible choices, 4, 5, and 6 is takes up 3. Thus, the chances of Taylor winning is:
![3/6=50\%](https://tex.z-dn.net/?f=3%2F6%3D50%5C%25)
The answer is D.
