For a standard normal distribution, find:

P(-1.91 < z < 0.4)

Answers

For a standard normal distribution, Probability (p) =  0.6273

What is a standard normal distribution?

A normal distribution, often known as a Gaussian distribution, is a form of the continuous probability distribution for a real-valued random variable in statistics.

A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.

To calculate probability, use the usual normal distribution. Because the standard normal distribution is a distribution function, the area under the curve between two points indicates the likelihood that variables will take on a range of values. The whole area under the curve is one, or one hundred percent.

Thus, for a standard normal distribution:

Using the standard normal table


P(-1.91 < z < 0.4)

= P (z<0.4) - P(z<-1.91)

= 0.6554 - 0.0281

= 0.6273

Hence,

Probability P(-1.91 < z < 0.4) under a standard normal distribution is:
P = 0.6273

What is true about the relationship between variable costs and economies of scale?​

Answers

Answer:

The cost per unit of fixed input decreases as output volume increases. A decrease in average variable costs (average non-fixed expenses), together with an increase in output, is another effect of economies of scale. This is caused by operational efficiency and synergies as a result of a rise in production scale.

Answers

Béla IV's statement in the fourth paragraph that the Hungarian people "cannot cease to be amazed" by the actions of the papacy most directly refers to the papacy's failure to aid the Hungarians while initiating European military campaigns in the Middle East is a true statement.

How did Hungary defeat Mongols?

The invasion was easily resisted, and the Mongols' invasion force was significantly reduced as a result of two significant military defeats, numerous lesser attacks, and several months of hunger. This was largely made possible by the military reforms and the new fortification network.

During the Mongol invasion of Europe, the Battle of Mohi (11 April 1241) served as the key conflict between the Mongol Empire and the Kingdom of Hungary. In Muhi (formerly Mohi), southwest of the Sajó River, it happened.

Note that between 1235 and 1270, Béla IV reigned as King of Hungary, Duke of Styria, and King of Croatia. King Andrew II's eldest son was crowned in 1214 on the initiative of a group of powerful noblemen during the reign of his father.
