The answer is 5.1 if you're looking for s all the work is in the picture
Answer:
21 bags. 1 Jolly rancher in each bag and 2 tootsie rolls on each bag.
Annual cost of insurance plan is $3975. The company pays 70 percent. How much does Jack pay?
100% - 70% = 30%
How many is that in dollars?
30% out of 3975 = 30% * 3975
We need to write percentage in decimal form
Jack pays $1192.5 annualy for this insurance plan
Assuming that year has 52 weeks, price per week would be:
$1192.5 / 52 = $22.93
He is paid biweekly so he needs to pay twice this amount:
$22.93 * 2 = $45.86
His insurance cost per paycheck is $45.86.
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
=>
=>
