Question

Bo Weevil works for Funny Bone Novelty products. One of their products is Fly Ice which is a piece of clear plastic shaped like an ice cube with one large nasty fly in the middle of the cube. Bo uses tsetse flies from Africa for the Fly Ice cubes. Bo just received a shipment of 500,000 tsetse flies. Bo noticed that some of the flies were defective since they had lost body parts during shipping. A sample of 400 flies from this shipment showed that 360 were of acceptable quality for use in the production of Fly Ice. a. What is your forecast for the total number of good flies in the 500,000 fly shipment? b. Construct an 95% confidence interval around your forecast.

Cicadas are flying, plant-eating insects. One species, the 13-year cicadas (Magicicada), spends five juvenile stages in underground burrows. During the 13 years underground, the cicadas grow from approximately the size of a small ant to nearly the size of an adult cicada. The adult body weights (BW) in grams and wing lengths (WL) in millimeters are given for three different species of these 13-year cicadas in the following table. It is of interest to determine if body weight is a significant predictor of wing length for a 13-year cicada. Considering all assumptions for a parametric test are satisfied, use the obtained jamovi © outputs below to answer the following: Provide an estimate for the correlation coefficient and interpret the relationship existing between the 13-year cicada’s body weight and wing length.
A friend of yours is trying to make a living selling helium-filled balloons. You think this might not be the smartest idea, but are glad to help when he asks. He wants to know whether there is a difference between using a self-seal balloon or a heat-sealed balloon to create long-lasting helium-filled balloons. Since he has quite a few of each type on hand, you randomly select 55 self-sealing balloons and 34 heat-sealed balloons. You then inflate each of them and leave them in a room, and record the time it takes for each balloon to hit the floor. You find that for the self sealing balloons, the average time is 3.2 days with a standard deviation of 1.1 days. For the heat-sealed balloons, the average time is 3.9 days with a standard deviation of 1.5 days. Let us be the true mean time it takes for a self-sealed balloon to hit the floor. Let uy be the true mean time it takes for a heat-sealed balloon to hit the floor. Test whether or not there is a difference between sealing methods in…

Lilo wants to know if equal proportions of students in her class know how to surf well, know how to surf a little or do not know how to surf. She randomly samples 60 students in her class and asks them if they know how to surf. Twenty students indicate that they do not know how to surf 'don't know', while 30 students indicate they know how to surf well 'know well,' and 10 students indicate they know how to surf ‘a little’. State the hypothesis being tested by Lilo (H0 and HA)? Test Lilo's hypothesis at α of .05. Enter the test statistic, critical value, and decision as part of your answer. Test statistic = Critical value = Do you reject or retain the null hypothesis that the slope is not different from zero? (Enter "Reject" or "Retain"):

Suppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table.
