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.
Step-by-step explanation:
See attached picture.
To find out how many students were left handed, we know that if 90% were right handed, then 10% have to be left handed.
30 students x 0.10 = 3 students left handed
Answer:
Domain :Set of all real values
Range : -5
Step-by-step explanation:
Here we see the blue line. Assuming it to be the graph of the function we are about to find Domain for.
Here we see that the graph is a straight line , parallel to x axis at y=-5
Hence the function will be
f(x)=-5
Also for every values of x, y =-5. Hence it is defined for all values of x. So the Domain is Set of All Real numbers
However,
For every value of x, the value of y is constant that is -5. Hence The range of f(x)=-5 is {-5}
Answer:
-500 < 200
Step-by-step explanation:
In inequality,
less than = <
greater than = >
Less than equal to = ≤
Greater than equal to = ≥,
Here, the given sentence is, loss of $500 is worse than a gain of $200
Generally, loss represents by an amount with a negative sign, That is, loss of $ 500 = - $ 500 Also, worse than is equivalent to less than. Thus, the required inequality would be, -500 less than 200 ⇒ -500 < 200
Answer:
Treatment: Epsom salt
Control Group: 50 people not receiving the Epsom salt to bathe
Treatment Group: 50 people that received the Epsom salt to bathe
Step-by-step explanation:
Treatment refers to the object in which is being used to treat the patients.
Control Group means the group that didn't receive any treatment, remained neutral to the experiment.
Treatment group is the group that received treatment.
