Lin is working on a scionce axperiment. She wants to dotormine wnether salt water bxoils faster than freshwater. She collects 10 samples of 100 milliliters of salt water and 10 sarmples of 100 milliters of freshwater. Sho places cach sample in a bcakor on a hot plate. She than recorda tho timo it takes to bxail for each group and find that the difference in mean timos for the groups is 24 secords. Lin writes a oomoutor program to recombino al tho data into all 184,756 posaibla diferent groupings and finds that 4,008 of the difforant groupings havo a difforeroa in mwns of at least 24 grams. Is there enough ovidence for Lin to conclude that the aliforence in means is duo to the addition of ualt to the wator? Explain or show your reasoning.

Lin is working on a science experiment. She wants to
determine whether salt water boils faster than freshwater.
She collects 10 samples of 100 milliliters of salt water
A company produces 10,000 plastic toys each day. A
sample of 25 toys are analyzed, and 2 of them are found
to not meet the standards of the company, so they are
labeled defective. A simulation is run in which 25 toys are
chosen out of 10,000 so that each toy chosen has an
8% chance of being defective. The simulation is run 200
times, and the moan proportion of defective toy is
0.081 with a standard deviation of 0.007.
and 10 samples of 100 milliiters of freshwater.
She places each sample in a bcaker on a hot plata. Sha
then records the time it takes to boil for each group and
find that the diflerence in mean times for the grcups is 24
seconds.
What is t'he margin of error basod on this simulation?
Lin writes a computor program to recombino al the data
into all 184,756 possible different groupings ana finds
that 4,008 of the difforant groupings have a differerce in
meens of at least 24 grams. Is there enough ovidence for
Lin to conclude that the alfforence in means is duo to the
addition of salt to the water? Explain or show your
raasoning.
