The output of a solar panel (photovoltaic) system depends on its size. A manufacturer states that the average daily production of its 1.5 kW system is 6.6 kilowatt hours (kWh) for Perth conditions. A consumer group monitored this 1.5 kW system in 20 different Perth homes and measured the average daily production by the systems in these homes over a one month period during October. The data is provided here. kWh 6.2, 5.8, 5.9, 6.1, 6.4, 6.3, 6.9, 5.5, 7.4, 6.7, 6.3, 6.2, 7.1, 6.8, 5.9, 5.4, 7.2, 6.7, 5.8, 6.9 1. Analyse the consumer group’s data to test if the manufacturer’s claim of an average of 6.6 kWh per day is reasonable. State appropriate hypotheses, assumptions and decision rule at α = 0.10. What conclusions would you report to the consumer group? (Hint: You will need to find Descriptive Statistics first.) 2. If 48 homes in the central Australian city of Alice Springs had this system installed and similar data was collected, in order to assess whether average daily production in…

Answer quickly please. Need answer ASAP. In a winter of an epidemic fu, the parents of 2000 babies were surveyed by researchers at a well-known pharmaceutical company to determine if the company's new medicine was effective after two days. Among 120 babies who had the fu and were given the medicine, 29 were cured within two days. Among 280 babies who had the flu but were not given the medicine, 56 recovered within two days. Is there any significant indication that supports the company's claim of the effectiveness of the medicine? Use α = 0.01

Toward the middle of the harvesting season, peaches for canning come in three types, early, late, and extra late, depending on the expected date of ripening. During a certain week, the data to the right were recorded at a fruit delivery station. Complete parts (a) through (d) below. 40 trucks went out carrying early peaches; 71 carried late peaches; 52 carried extra late peaches; 26 carried early and late; 32 carried late and extra late; 11 carried early and extra late; 6 carried all three; 5 carried only figs (no peaches at all). a) How many trucks carried only late variety peaches? trucks (Type a whole number.) (b) How many carried only extra late? trucks (Type a whole number.) (c) How many carried only one type of peach? trucks (Type a whole number.)

Fruit flies have built-in circadian rhythms that keep time in the absence of external stimuli. Several genes have been shown to be involved in internal timekeeping, including per (period) and tim (timeless). Mutations in these two genes, and in other genes, disrupt timekeeping abilities. Interestingly, these genes have also been shown to be involved in other time-related behavior. Individuals that carry particular mutations of per and tim have been shown to copulate for longer than individuals that have neither mutation. The following table summarizes some data on the duration of copulation for flies that carry either the per mutation or the tim mutation: Mutation Mean copulation duration (min) Standard deviation Sample size per 17.5 3.37 14 tim 19.9 2.47 17 Do the populations carrying these mutations have different variances in copulation durations? Carry out the appropriate test using α =0:05 Do these two mutations lead to different mean…
Overhead Door (OD) Corporation’s founder, C. G. Johnson, invented the upward-lifting garage door in 1921 and the electric garage door opener in 1926. Since then OD has been a leading supplier of commercial, industrial, and residential garage doors sold through a nationwide network of more than 450 authorized distributors. They have built a solid reputation as a premier door supplier, commanding 15 % share of the market. Suppose that customers assess door quality first in terms of the ease of operation, followed by its durability. The quality improvement team (QIT) might then assign an engineering team to determine the factors that contribute to these two main problems. Smooth operation of a garage door is a critical quality characteristic that affects both problems: If a door is too heavy, it’s difficult and unsafe to balance and operate; if it’s too light, it tends to buckle and break down frequently or may not close properly. Suppose the design engineers determine that a standard…
We want to make a time study on a worker-machine cycle. To do that, we observe times via the snapback method. This cycle comprises threeelements: x, y, and z. Elements x and y are worker-controlled and performance rated at 100%. Element z is machine-controlled. Besides, it is giventhat elements y and z are performed at the same time. The PFD allowance = 17% and the machine allowance = 10%. At each cycle, the systemproduces one work piece. Q: Find (a) the normal time and (b) standard time for the cycle. a) a: 2,25; b: 3,6155b) a: 3,15; b: 3,7855c) a: 2,25; b: 2,5625d) a: 3,15; b: 2,5625e) a: 3,15; b:3,6155
Consider a hypothetical study that suggests that job satisfaction predicts the extent to which employees perform well on the job. A follow-up investigation supports the mechanism underlying this relationship: satisfied employees show up to work more energized, which in turn goes on to influence their performance. In the space below, match the variables in the study with the corresponding name. Independent variable a. Energy at work b. job performance c. job satisfaction d. This type of variable is not mentioned in this example Mediator variable a. Energy at work b. job performance c. job satisfaction d. This type of variable is not mentioned in this example
