Lalli long jumper is a teacher in a crowded school here in the city. He is very interested in long jump and he decided to study the long jump ability of the school's students. He held a long jump competition where all the students at the school took part and he measured the length of the students' jumps. Let us now assume that the length of the jump among the students at the school follows a normal distribution with an average of 4 meters and a standard deviation of 1 meter. Lalli randomly selected 100 participants from the long jump competition and asked them if they enjoyed long jump. 62 respondents said they enjoyed long jump. Lalli used the data to create a 95% confidence interval for the proportion of students who enjoy long jump. What is the lower limit of the safety gap? a.) 0.45 b.) 0.52 c.) 0.58 d.) 0.61 e.) 0.71

Tech Worx magazine reported that91%of software engineers rate the company they work for as "a good place to work." You are a headhunter, and as such you state that the percentage in the report is not correct.

Hi Can you please fill out the blanks?
A container of car antifreeze is supposed The whole three 3785 mL of the liquid. Realizing that fluctuations are in inevitable, Quality control manager of the Taconic chemical company wants to be quite sure that the standard deviation is less than 30 mL otherwise some containers would overflow while others would not have enough of the coolant she selects a simple random sample of 24 containers and find that mean it's three 789 mL in the scanner deviation is 42.8 mL use the sample results to construct a 99% confidence interval for the true value of Sigma does this confidence interval suggest that the variation is that an acceptable level?
Number 2 please
