An F test has Sample 1 n1 = 28 and Sample 2 n2 = 34. What is df1?

Sample 1 has n1 = 200 and x1 = 160. Sample 2 has n2 = 300 and x2 = 210. What is p̄?

Sample 1 has p̂1 = 0.82, n1 = 500. Sample 2 has p̂2 = 0.76, n2 = 400. Use p̄ = 0.793 and q̄ = 0.207. Compute TS. Round to 3 decimals.

Dee’s Burgers claims its mean burger meat weight is greater than Tom’s. A random sample of 35 Dee’s burgers has x̄1 = 8.1 and s1 = 0.15. A random sample of 40 Tom’s burgers has x̄2 = 8.0 and s2 = 0.20. Use α = 0.05. The right-tail critical value is 1.645. Is the claim supported? Answer “supported” or “not supported”.
