The weights of soy patties sold by Veggie Burgers Delight are normally distributed. A random sample of 15 patties yields a mean weight of 3.75 ounces with a sample standard deviation of 0.5 ounces. At the 0.05 level of significance, perform a hypothesis test to see if the true mean weight is less than 4 ounces. The correct calculated value of the test statistic is (Use JMP to answer this question).

solution
Test statistic = t
= (
- 
) / s / 
n
= (3.75-4) / 0.5 /
15
t= -1.93
Test statistic = t= - 1.93

2) The weights of soy patties sold by Veggie Burgers Delight are normally distributed. A random sample of 15 patties yields a mean weight of 3.8 ounces with a sample standard deviation of 0.5 ounces. At the 0.05 level of significance, perform a hypothesis test to see if the true mean weight is less than 4 ounces. Use a level of significance of 0.05.

An attorney claims that more than 25% of all lawyers advertise. A random sample of 200 lawyers in a certain city showed that 63 had used some form of advertising. At a 0.05, what would be your conclusion regarding the hypothesis test? O Accept the null hypothesis and the test is insignificant. O Reject the null hypothesis and the test is significant O Cannot be determined. A researcher wishes to see if the average weights of newborn male infants are...

Research studies have shown that the weights of common wood pigeons tend to be normally distributed...
Research studies have shown that the weights of common wood pigeons tend to be normally distributed with a mean weight of 450 grams. A scientist livinv in Athens Greece, has noticed smaller pigeons in the city recently and questions whether some environmental factor is causinf the city pigeons to be of lesser average weight than would normally be expected. To investigate this matter she conducts a hypothesis test at the a = 0.05 level of significance. After collecting a random...

(1 point) When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of 61.4 oz. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces). 66.8, 65.9, 64.2, 65.2, 64.1, 64.1, 69.8, 65.3, 63, 65.7 Use the a = 0.05 significance level to test the claim that the mean weight is higher with the enriched feed. (a) The sample mean is ž = (b)...

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A coin mint has a specification that a particular coin has a mean weight of 2.5 g. A sample of 33 coins was collected. Those coins have a mean weight of 2.49615 g and a standard deviation of 0.01242 g. Use a...

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Use the traditional method. Identify the null and alternative hypotheses, test statistic, critical value(s), and state the final conclusion that addresses the original claim.
