A sporting goods manufacturer claims that the variance of the strengths of a certain fishing line spool is 15.9. A random sample of 15 fishing line spools has a variance of 28. At α = 0.05, is there enough evidence to reject the manufacturer’s claim? Assume population of this variable is normally distributed.

A manufacturer of sports equipment has developed a new synthetic
fishing line that the company claims has a mean breaking strength
of 7.5 kilograms with a standard deviation of 0.7 kilogram. Test
the hypothesis that µ = 7.5 kilograms, against the alternatives:
(a) µ 6= 7.5; (b) µ > 7.5; (b) µ < 7.5. Given that a random
sample of 50 lines is tested and found to have a mean breaking
strength of 7.8 kilograms. Use a 0.01 level of...

A manufacturer of sports equipment has developed a new synthetic
fishing line that the company claims has a mean breaking strength
of 8 kg with a standard deviation of 0.5 kg. To test the claim, a
random sample of 50 lines is tested and found to have a mean
breaking strength of (7.8 kg) and a standard deviation of (0.7 kg).
Could you conclude that the manufacturer claim justified at 0.01
level of significance?( state any assumptions

A manufacturer has developed a new fishing line, which the
company claims has a mean breaking strength of 14.5 kilograms with
a standard deviation of 0.8 kilograms. Believing the mean breaking
strength is less than what company has claimed, a customer
protection agency took a random sample of 40 such fishing lines and
found that the mean breaking strength for this sample is 13.2
kilograms. Given the breaking strength of all such lines have a
normal distribution, test whether the...
