Question:
A soft drink manufacturer is using a "winning" cap as a sales promotion. The purchaser can get a prize if they buy a bottle that has a "Winner" symbol under the cap. Winning symbol caps are placed randomly on 5% of the bottles.
You buy a six-pack of the soft drink.
a) State the exact probability distribution that applies to this circumstance.
b) What is the probability that you win something? Give clear notation of the probability calculated.
c) What is the Poisson approximation to this distribution? Estimate the probability that you win something using this approximation.
d) Comment on the results of the two calculations.
a score that is 6 points below the mean corresponds to a z- score of z -0.50. what is the population standard
The standard deviation of this poll is 4%. What would be the standard deviation if the sample size were increased from 93 to 187?
If they find a significant increase in the proportion of items that must be rejected, they will halt the assembly process until the problem can be identified and repaired.
Samples of size 49 are taken from a population with a σ of 17. If the mean of the sample is 25, what is the confidence interval at the 90% confidence level
Stats Questions Set. Which of the following statements correctly compares the t -statistic to the z -score when creating a confidence interval?
Determine the best replacement policy over the next five years?
You need to estimate the mean number of travel days per year for outside salespeople. The mean of a small pilot study was 150 days, with a standard deviation of 42 days.
Use any method to decide whether to rejects or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim.
A company has 25 cars of this model in its fleet. What is the level L such that the probability that the average NOX level for the fleet is greater than L is only 0.01?
The probability is 90% that the sample percentage will be contained within what symmetrical limits of the population percentage?
Prepare a 1,050- to 1,750-word paper describing the results of a hypothesis test of one population mean or population proportion.
The comparison distribution at which the null hypothesis should be rejected, (b) the Z score on the comparison distribution for the sample score, and (c) your conclusion. Assume that all populations are normally distributed.
