Answer:
0
Step-by-step explanation:
H0 : μ = 840
H1 : μ < 840
Sample size, n = 49
Standard deviation, s = 14
Test statistic = (xbar - μ) ÷ (s/√(n))
Test statistic = (830 - 840) ÷ (14/7)
Test statistic = - 10 / 2
Test statistic = - 5
The Pvalue ;
Pvalue = P(Z < - 5) = 0 (Z probability calculator)
The Pvalue = 0
