The average weight of a jelly bean is known to be 1.10 grams. It’s known to have a standard deviation of 0.2 grams. 100 jelly beans have been weighted and found an average weight of 1.25 grams. Is there evidence that the known weight is true? Test it with a 0.05 level of significance.Find the: Parameter of interest: ?Null hypothesis: ?Alternative hypothesis: ?Test statistic: ?Reject H0 if: ?Computations: ?Conclusion: ?

Step 1
Null hypothesis (H0): The null hypothesis is that the true average weight of a jelly bean is 1.10 grams. Mathematically, this can be written as H0: μ = 1.10. Alternative hypothesis (H1): The alternative hypothesis is that the true average weight of a jelly bean Show more…

'The US Mint has a specification that pennies have & mean weight of 2.5 g Assume that weights of pennies have a standard deviation of 0.0165 g. A simple random sample of 37 pennies manufactured after 1983 gives mean weight of 2.499 g: Use P-value method to test the claim that the sample is from population with a mean that is less than 2.5 g The significance level is specified asa =0.10. Identify the null hypothesis, alternative hypothesis, test statistic, P-value and state your conclusion about the claim'
Test the hypothesis. (Follow the 6 steps in hypothesis testing). 1. It is claimed that the average weight of babies at birth is 3.4 kg. The average weight of a random sample of 30 newly born babies was determined. It was found out that the average weight was 3.1 kg. Is there a reason to believe that the average weight of babies at birth is different from 3.4 kg? Assume that the population standard deviation is 2.1 kg. Use 0.05 level of significance.
