A pharmaceutical company is conducting a study on whether or not their new vaccine is effective in preventing chicken pox. The r

esearchers rejected the null hypothesis and stated that the vaccine was effective. However, subsequent studies found out that the vaccine did not have any effect on combating chicken pox. What type of error did the researchers make

Fed [463]2 years ago
5 0

Answer:

The answer is "Type 1 error".

Step-by-step explanation:

The error of type I, frequently known as a 'false positive': its error in judgment that perhaps a null hypothesis is simply rejected. This is the mistake of accepting a possible (actual interest hypothesis) hypothesis whenever the results could be attributed to chance since the researchers deny, if valid, the null hypothesis.

If w = 10 units, x= 5 units, and y= 6 units, what is the surface area of the figure?
qwelly [4]

Answer:

  456.2 units²

Step-by-step explanation:

The area of the square base is ...

  base area = w² = (10 units)² = 100 units²

The lateral area is 4 times the area of one rectangular face:

  lateral area = 4wx = 4(10 units)(5 units) = 200 units²

The area of one triangular face is half the product of its base length (w) and its slant height (h). The latter is found using the Pythagorean theorem:

  h² = y² +(w/2)² = (6 units)² +((10 units)/2)² = 61 units²

  h = √61 units

So, the area of 4 triangles is ...

  area of triangular faces = 4(1/2)wh = 2(10 units)(√61 units) ≈ 156.2 units²

__

Now we have the areas of the parts, so we can add them together to get the total surface area:

  surface area = base area + lateral area + area of triangular faces

  = 100 units² + 200 units² + 156.2 units²

  surface area = 456.2 units²
