I need help with homewrok questions!! Bil-Jac is a family-owned and -operated pet food company with its headquarters in Medina, Ohio. This is where Bil-Jac products are formulated and produced, made exclusively by the Kelly Foods Corporation. Bil-Jac weighs bags of dog food prior to shipment to stores. The bags of dog food have a population mean of 25 pounds, and a population standard deviation of 0.75 pounds. Based on a sample size of 64 bags, the probability that the average weight of the bags will exceed 25.18 lbs. is . Use only the appropriate formula and/or statistical table in your textbook to answer this question. Report your answer to 4 decimal places, using conventional rounding rules. Based on a sample size of 64 bags, the probability that the average weight of the bags will be between 24.76 and 24.82 lbs. is . Use only the appropriate formula and/or statistical table in your textbook to answer this question. Report your answer to 4 decimal places, using conventional rounding rules. Based on a sample size of 64 bags, the probability that the average weight of the bags will be less than 25.27 lbs. is . Use only the appropriate formula and/or statistical table in your textbook to answer this question. Report your answer to 4 decimal places, using conventional rounding rules. If random samples of 64 bags are repeatedly drawn from this population and the mean number of pounds in each sample is recorded, 90% of the sample means should be below pounds. Use only the appropriate formula and/or statistical table in your textbook to answer this question. Report your answer to 2 decimal places, using conventional rounding rules.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
