### Hypothesis Testing for Left-Handedness Among Males and Females**Problem Statement:**In a random sample of males, it was found that 22 write with their left hands and 220 do not. In a random sample of females, it was found that 73 write with their left hands and 449 do not. Use a 0.05 significance level to test the claim that the rate of left-handedness among males is less than that among females. Complete parts (a) through (c) below.---#### Part (a): Formulating the Hypotheses**Task: Test the claim using a hypothesis test.**Consider the first sample to be the sample of males and the second sample to be the sample of females. What are the null and alternative hypotheses for the hypothesis test?---**Hypothesis Options:**- **Option A:** \[ H_0: p_1 = p_2 \] \[ H_1: p_1 > p_2 \]- **Option B:** \[ H_0: p_1 = p_2 \] \[ H_1: p_1 \neq p_2 \]- **Option C:** \[ H_0: p_1 \le p_2 \] \[ H_1: p_1 \neq p_2 \]- **Option D:** \[ H_0: p_1 = p_2 \] \[ H_1: p_1 < p_2 \]- **Option E:** \[ H_0: p_1 \neq p_2 \] \[ H_1: p_1 = p_2 \]- **Option F:** \[ H_0: p_1 \ge p_2 \] \[ H_1: p_1 \neq p_2 \]---To proceed with hypothesis testing, the selection of the correct hypothesis pairs that match the claim being investigated is essential.**Explanation:**- $ p_1 $ represents the proportion of males who are left-handed.- $ p_2 $ represents the proportion of females who are left-handed.The claim to test is "the rate of left-handedness among males is less than that among females."### **Correct Hypothesis Selection:**Given the claim

The given claim is that the rate of left-handedness among males is less than that among females.

Answered: In a random sample of males, t was…

The data in the accompanying table give the weights (in g) of randomly selected quarters that were minted after 1964. The quarters are supposed to have a median weight of 5.670 g. Use the sign test and a 0.05 significance level to test the claim that the median is equal to 5.670 g. Do quarters appear to be minted according to specifications? Click the icon to view the data. What are the null and alternative hypotheses? O A. Ho: Median weight = 5.670 g H₁: Median weight # 5.670 g O C. Ho: Median weight ≤ 5.670 g H₁: Median weight > 5.670 g Find the test statistic.

Suppose that you want to perform a hypothesis test based on a simple random paired sample to compare the means of two populations. For each part, decide whether you would use the paired t-test, the pairedWilcoxon signed-rank test, or neither of these tests. Preliminary data analyses of the sample of paired differences suggest that the distribution of the paired-difference variable is a. approximately normal.b. highly skewed; the sample size is 20.c. symmetric bimodal
