**Constructing a 95% Confidence Interval for Watermelon Weights**In this exercise, you have measured the weights of 30 watermelons and found that they have a mean weight of 43 ounces. Given that the population standard deviation is 3 ounces, your task is to construct a 95% confidence interval for the true population mean watermelon weight.### Steps to Construct the Confidence Interval1. **Identify the Sample Mean and Standard Deviation:** - Sample mean ($\bar{x}$): 43 ounces - Population standard deviation ($\sigma$): 3 ounces 2. **Sample Size:** $n = 30$3. **Determine the Z-Score for a 95% Confidence Level:** - For a 95% confidence level, the Z-score is approximately 1.96 (based on standard normal distribution).4. **Calculate the Standard Error (SE):** \[ SE = \frac{\sigma}{\sqrt{n}} = \frac{3}{\sqrt{30}} \]5. **Calculate the Margin of Error (ME):** \[ ME = Z \times SE = 1.96 \times \frac{3}{\sqrt{30}} \]6. **Construct the Confidence Interval:** - Lower limit: $\bar{x} - ME$ - Upper limit: $\bar{x} + ME$By filling in the required values and performing the calculations, you will obtain the confidence interval expressed as decimals to two places.### Enter Your ResultsPlease enter your calculated lower and upper limits in the designated response fields in ounces.---**Note:** If you need assistance with any part of this exercise, feel free to message your instructor for guidance.**Submit your answers** using the 'Submit Question' button once you have completed the calculations.

This problem is fill in the blank. Just choose the correct answers. Thank you for your help A psychologist is studying the self-image of smokers, as measured by the self-image (SI) score from a personality inventory. She would like to examine the mean SI score, μ, for the population of all smokers. Previously published studies have indicated that the mean SI score for the population of all smokers is 85 and that the standard deviation is 10, but the psychologist believes that the value for the mean has increased. She plans to perform a statistical test. She takes a random sample of SI scores for smokers and computes the sample mean to be 95. Based on this information, answer the questions below. 1. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0: (choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to. (choose one) 85, 95, or 10. H1: (Choose one) less than,…

Suppose a researcher wants to test if the average diastolic blood pressure in African-Americans is different than the average diastolic blood pressure in the general population. Note that the average diastolic blood pressure in the general population is 70 mmHG. The researcher retains the null hypothesis, so she therefore concludes... Group of answer choices The mean diastolic blood pressure in African-Americans is equal to that of the general population The mean diastolic blood pressure in African-Americans is different than that of the general population

You get hired as a server at a local restaurant, and the manage tells you that servers tips are $42 on average but vary about $12 (mean =42, standard deviation =12). You decide to track your tips to see if you make a different amount, but because this is your first job as a server, you don't know if you will make more or less in tips. After working 16 shifts, you find that your average mightly amount is $44.50 from tips test for a difference between this value and the population mean at the a=0.05 level of significance.
