Fill in the blanks to complete the 4 part conclusion. There is suggestive, but inconclusive evidence the Velvetleaf seed beetle
is successful at weed control. The sample estimates the average percent of seeds to be infected by the beetle is 5.164, with a 95% confidence interval of 3.699 to 6.629 . We fail to reject the null hypothesis at a 0.05 significance level..
a) how suggestive or inconclusive
b) lower and upper bounds
c) reject or fail to reject
a) how suggestive or inconclusive
b) lower and upper bounds
c) reject or fail to reject
1 answer:
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.

Answer:
length of the curve = 8
Step-by-step explanation:
Given parametric equations are x = t + sin(t) and y = cos(t) and given interval is
−π ≤ t ≤ π
Given data the arrow the direction in which the curve is traces means
the length of the curve of the given parametric equations.
The formula of length of the curve is
Given limits values are −π ≤ t ≤ π
x = t + sin(t) ...….. (1)
y = cos(t).......(2)
differentiating equation (1) with respective to 'x'
differentiating equation (2) with respective to 'y'
The length of curve is
on simplification , we get
here using sin^2(t) +cos^2(t) =1 and after simplification , we get
again using formula, 1+cost = 2cos^2(t/2)
Taking common we get ,
length of curve =
length of the curve is = 4(1+1) = 8
<u>conclusion</u>:-
The arrow of the direction or the length of curve = 8
