If a fourth species of neutrino were discovered, what might it mean for the standard hot big bang model?.
Nuetrino are massless charged particles. They play a very important role in energy balancing during reactions and make many reactions possible.
If a fourth species is found Standard hot big bang model will have to be recalculated as many implied reactions will become unviable to explain.

What elements were created in the big bang? During what time period in the early universe did nucleosynthesis occur? Why just during this period? Describe qualitatively why the hot big bang model predicts that the universe should contain ∼26% by mass helium. Why is the present deuterium abundance sensitive to the value of Ω?
The "classic" Big Bang theory explains that the Universe was originally very hot and very dense and that this leads to some clear predictions that have been experimentally verified.However, there were some observed properties of the Universe that the classic Big Bang theory couldn't explain. Explaining these additional properties of the Universe required the development of the model of cosmic inflation in the 1980s, which has some additional predictions we are attempting to verify with experiments today. What properties of...
In a sample of size 14 hot dogs, the mean calorie content was 329 with standard deviation 36. Were interested in determining if the population mean is different than 350. What's the p-value? Give you answer as a decimal value accurate to 3 decimal places.
QUESTION 6 A new species of sea crab has been discovered, and an experiment conducted to determine whether or not the animal can regulate its temperature. If the animal can maintain a body temperature different from the surroundings, this would be considered evidence of regulating capability. Ten of these sea crabs were exposed to ambient temperature of 24 degrees Celsius. Their body temperatures were measured with the results below: 24.33 24. 61 24.67 24.64 24.42 24.97 25.23 24.73 24.90 24.44...

A species of bird is approximately normally distributed with mean height of 80cm and standard dev. of 5cm. A. What proportion of these birds are taller than 86.5 cm? B. In a random sample of 6 birds, what is the probability that the average height is greater than 86 cm? C. What is the minimum height for the top 15% of birds? Show your work please!

A nutrition laboratory tests 50 "reduced sodium" hot dogs, finding that the mean sodium content is 317mg, with a standard deviation of 36 mg. a) Find a 95% confidence interval for the mean sodium content of this brand of hot dog. b) What assumptions have you made in this inference? Are the appropriate conditions satisfied? c) Explain clearly what your interval means. A nutrition laboratory tests 50 "reduced sodium" hot dogs, finding that the mean sodium content is 317 mg,...
