Answer:
11
Step-by-step explanation:
Pulg in 2 into the equation x+3^2
I dont know if theres supposed to be a parenthese like but if there isn't then it would be 2+ which is 2+9
if there is parenthese... it would be:
= =25

Answer:
Your question is VERY hard to read so I'm gonna take the points and go..
Answer:
a) P(X>825)
b) This low value of probability of the sample outcome (as 825 voters actually did vote) suggests that the 60% proportion may not be the true population proportion of eligible voters that actually did vote.
Step-by-step explanation:
We know a priori that 60% of the eligible voters did vote.
From this proportion and a sample size n=1309, we can construct a normal distribution probabilty, that is the approximation of the binomial distribution for large samples.
Its mean and standard deviation are:
Now, we have to calculate the probabilty that, in the sample of 1309 voters, at least 825 actually did vote. This is P(X>825).
This can be calculated using the z-score for X=825 for the sampling distribution we calculated prerviously:
This low value of probability of the sample outcome (as 825 voters actually did vote) suggests that the 60% proportion may not be the true population proportion of eligible voters that actually did vote.
Option (A) is correct, the conjugate of denominator will be √10+2
