Answer:
This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.
Explnation:
z = (x - mu)/sd
z = (2625 - 2600)/50 = 25/50 = 0.5.
Consulting the z-table, P(z <= 0.5) = 0.6915.
P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.
I hope this helped! <3

Answer:
0.1527
Step-by-step explanation:
Standard Deviation = √p × q/n
Reynolds: 63%
Bachmann: 37%
n = 100
Standard Deviation = √0.63 × 0.37/100
= √(0.02331)
= 0.1526761278
≈ 0.1527
Answer:
C) The confidence interval is not biased.
Step-by-step explanation:
When a relationship between two variables is observed the confidence interval should not be biased. If the confidence interval is found to be biased then the observed results will be reliable and accurate. Regression analysis of heart rate and maximal oxygen uptake is analyzed and the correlation will not be equal to zero. This means there will be some correlation between the two variables.
