Which is a raw score that has been transformed into standard deviation units?
1). z score
2). SDU score
3). t score
4). xxx score

Z Score

$Z = \frac{X - \mu}{\sigma}$

Explanation: A z-score (also called a standard score) is a raw score that has been transformed into standard deviation units. It tells us how many standard deviations a data point is away from the mean.

Components of the formula:

1. Z = Z-score (standardized score)
2. X = Raw score (individual data point)
3. μ = Mean of the dataset
4. σ = Standard deviation of the dataset

Interpretation:

1. A positive z-score (𝑍>0) means the data point is above the mean.
2. A negative z-score (𝑍<0) means the data point is below the mean.
3. A z-score of 0 means the data point is exactly at the mean.

Z-scores are useful in comparing data points from different distributions and in probability calculations using the standard normal distribution.

• In an alloy, zinc and copper are in the ratio 1 : 2. In the second alloy, the same elements are in the ratio 2 : 3. If these two alloys be mixed to form a new alloy in which two elements are in the ratio 5:8, the ratio of these two alloys in the new allow
• Nidhi received simple interest off Rs. 1200 when invested Rs x at 6% p.a. and Rs y at 5% p.a. for 1 year. Had she invested Rs. x at 3% p.a. and Rs. y at 8% for that year, she would have received simple interest of Rs 1,260. Find the values Rs. x an y.
