Given:
13 pounds and 7 ounces
convert to kilograms:
1 kilogram = 2.20462 pounds
1 kilogram = 35.274 ounces
13 pounds * 1 kg/2.20462 pounds = 13 kg/2.20462 = 5.8967 kg
7 ounces * 1kg/35.274 ounces = 7 kg/35.274 = 0.1984
5.8967 kg + 0.1984 = 6.0951 kg. rounded up to 6.10 kgs.
Answer:
Let X = score of final exam.
X~normal(23, 16)
(a)
percentage of score between 19 and 27
= P(19 < X < 27)
= P((19-23) / sqrt(16) < Z < (27 - 23) / sqrt(16))
= P(-1 < Z < 1)
= 1 - P(Z <= -1) - P(Z >= 1)
= 1 - P(Z >= 1) - P(Z >= 1)
= 1 - 2*P(Z >= 1)
= 1 - 2(0.1587)
= 0.6826
= 68.26%
According to Normal Distribution Table
P(Z>=1) = 1 - P(Z<1) = 1-0.8413
So the final percentage is 68.26%
Answer:
a) There is suggestive evidence the velvet leaf seed is successful at weed control.
b) Lower bound: 3.699 Upper bound: 6.629
c) Since the confidence interval contains the average percent of seeds to be infected by the beetle (5.164), so we fail to reject the null hypothesis at the specified level of significance.
