A genetic experiment involving peas yielded one sample of offspring consisting of 442 green peas and 142 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 24% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.**What are the null and alternative hypotheses?**- A. \( H_0: p = 0.24 \) \( H_1: p > 0.24 \)- B. \( H_0: p \neq 0.24 \) \( H_1: p = 0.24 \)- C. \( H_0: p \neq 0.24 \) \( H_1: p > 0.24 \)- D. \( H_0: p = 0.24 \) \( H_1: p < 0.24 \)- E. \( H_0: p = 0.24 \) \( H_1: p \neq 0.24 \)- F. \( H_0: p \neq 0.24 \) \( H_1: p < 0.24 \)**What is the test statistic?**\[ z = \square \](Round to two decimal places as needed.)**What is the P-value?**P-value = \(\square\) (Round to four decimal places as needed.)**What is the conclusion about the null hypothesis?**- A.

A psychologist wants to test whether there is any difference in puzzle-solving abilities between boys and girls. Independent samples of eleven boys and seven girls were chosen at random. The boys took a mean of 37 minutes to solve a certain puzzle, with a standard deviation of 4.8 minutes. The girls took a mean of 35 minutes to solve the same puzzle, with a standard deviation of 4.5 minutes. Assume that the two populations of completion times are normally distributed, and that the population variances are equal. Can we conclude, at the 0.10 level of significance, that the mean puzzle-solving times for boys, μ1 is greater than the mean puzzle-solving times for girls, μ2? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. a. State the null hypothesis H0 and the alternative hypothesis H1. b. Find the value of the test statistic. (Round to three or more decimal…
A poll of 1086 Americans showed that 47.1% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.01 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.
Test the research hypothesis that there is a difference in weights between the two groups at the 0.05 significance level? Assume the equality of variance, adequate sample size, and normal distribution for both the groups to test the hypothesis. X1 = 200 X2 = 198 n1 = 17 n2 = 17 s1 = 2.45 s2 = 2.35 Please show all the necessary steps of hypothesis testing to answer this question.
If the variance in the weights of one sample of 12 oz. cookies is 3 oz. and the variance in a second sample, made in another factory, is only 1 oz. is there a real difference in variances between the two? (Estimate at 95% probability level, using 2-tail test). Use the appropriate test statistic to determine this, and assume there are 9 degrees of freedom for each sample. Yes no maybe none of the above.
Conduct a two-sample t-test at a 1% level of significance to find out if the mean U.S. stock return significantly outperforms the mean US bond return using the monthly data covering the sample period 1980-2020. Draw your conclusion by both the P value method and the Critical Value Method.

A poll of 1182 Americans showed that 47.2% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.01 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. Begin by using the original claim to create a null hypothesis and an alternative hypothesis. The null hypothesis (denoted by Ho) is a statement that the value of a population parameter (such as proportion, mean, or standard deviation) is equal to some claimed value. The alternative hypothesis (denoted by H, or H, or HA) is a statement that the parameter has a value that somehow differs from the null hypothesis.
The Covallis Reporter claimed in a recent issue that the average assembly time for the new Ford CoolCar is approximately 39 hours. Recently a modification in the assembly procedure was made to reduce the average assembly time of the CoolCar. A systematic random sample of 45 vehicles finds that the average assembly time is 38.5 hours. Experience with the new assembly method indicates that Is there evidence that the new method reduced the assembly time on average? Use a significance level of 0.05 Question of interest: Parameter of interest (notation and description in context): Significance level: State the null and alternative hypotheses.

Suppose that 90% of Narnians are children, that Narnian children have normallydistributed BMIs with a mean of 25 kg/m2and variance of 64 (kg/m2) 2, and that Narnianadults have normally distributed BMIs with a mean of 30 kg/m2and variance of 100(kg/m2)2. WHO currently categorizes BMIs greater than 30 as obese.a. What is the prevalence of obesity among Narnian children?b. What is the prevalence of obesity among Narnian adults?c. What is the overall prevalence of obesity among Narnians?d. Are age and obesity statistically independent in Narnia?e. What proportion of Narnians are obese children?f. What proportion of obese Narnians are children?
A researcher decides to measure anxiety in group of bullies and a group of bystanders using a 23-item, 3 point anxiety scale. Assume scores on the anxiety scales are normally distributed and the variance among the group of bullies and bystanders are the same. A group of 30 bullies scores an average of 21.5 with a sample standard deviation of 10 on the anxiety scale. A group of 27 bystanders scored an average of 25.8 with a sample standard deviation of 8 on the anxiety scale. You do not have any presupposed assumptions whether bullies or bystanders will be more anxious so you formulate the null and alternative hypothesis based on that.
