In a random sample of 800 U. S. teens, 336 are worried that they or someone in their family will become a victim of a terrorist. A survey of U. S. teens says that 35% of teens are worried that they or someone in their family will become a victim. At a significance level of 0.01, can you support the claim if you believe the true proportion is higher than the sample shows? A) Write the null and alternative hypotheses.

B) Check to see if the conditions are met.

C) Identify the test statistic and P-value.

D) State the conclusion in the context of the problem.

C

Step-by-step explanation:

what ever

Step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
