- ACTIVITY 1: 1. A factory, manufacturing light-emitting diode (LED) bulbs, claims that the average lifespan of their light bulbs is 50, 000 hours. To confirm if this claim is valid, a quality control manager got a sample of 50 LED bulbs and obtained a mean lifespan of 40, 000 hours. The standard deviation of the manufacturing process is 1, 000 hours. Do you think the claim of the manufacturer is valid at the 5% level of significance? STEP 1.

- A factory deep in a fjord has over a long time released a certain type of heavy metal, and a mappingof the concentration of the heavy metal on the seabed in the area around the factory has been carried out. It's for eachsample recorded heavy metal concentration, distance to the factory (in km) and depth (in meters). You findthe data in the file Heavy metal data.We will initially look at the connection between heavy metal concentration and distance to the factory,and fit a linear regression model Y = α + βx + e where we use heavy metal concentration asY -variable and distance as x-variable.1.) Briefly explain why it is reasonable to use heavy metal concentration as the Y variable and distanceas x-variable and not the opposite.2.) Give practical interpretations of the α-parameter and the β-parameter in the model in this situation.2.) What does it mean in practice in this specific situation if β < 0, if β = 0 and if β > 0?arrow_forwardSpecial dyes have been developed that only bind to DNA. The intensity of the color is directly related to the quantity of DNA present in the cell. A haploid cell would have a “low” amount of color, a cell in G1 would have a “medium” amount of color, and a cell in M phase would have a “high” amount of color. Is this sort of assessment quantitative, qualitative or semi-quantitative?
