Answer:
a
The 95% confidence interval is
b
The sample proportion is
c
The critical value is
d
The standard error is
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number of defective is k = 18
The null hypothesis is
The alternative hypothesis is
Generally the sample proportion is mathematically evaluated as
Given that the confidence level is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the standard of error is mathematically represented as
substituting values
The margin of error is
=>
=>
The 95% confidence interval is mathematically represented as
=>
=>
Answer:
0.07
Step-by-step explanation:
it is given odds in favor of a win is 7 to 93
we have to find the degree of likelihood as a probability
total sample space =7+93=100
so the degree of likelihood as a probability =
so we can conclude that the probability will be 0.07 which is very less so the chances of win in the casino is very less
