Help on my last 5 questions. can't afford to get it wrong

True or false? a clustering appointment type is when patients with similar problems are booked consecutively on the same day.

Vadim26 [7]

The statement that "A clustering appointment type is when patients with similar problems are booked consecutively on the same day" is true. Clustering is type of appointmnet scheduling. In this type of scheduling patients with similar problems are booked consecutively. A block of time is set aside for particular types of cases.

Imagine that you attempted to recreate Mendel's work with garden peas. You began by crossing true breeding violet-flowered, tall

salantis [7]

Answer:

(a) 90

(b) 30

(c) 30

(d) 10

F2 data for stem length (tall:dwarf) is consistent with Mendel's law of segregation.

F2 data for stem length (tall:dwarf) and flower color (violet:white) is consistent with Mendel's law of independent assortment

Explanation:

The F2 phenotypes are supposed to be in 9:3:3:1 according to Mendelian law. The total number of F2 progeny is: 80 + 36 + 39 + 5 = 160

(a) Hence, the expected number of tall, violet plants will be:

9/16 x 160 = 90

(b) Expected number of tall, white plants will be:

3/16 x 160 = 30

(c) Expected number of dwarf, violet plants will be:

3/16 x 160 = 30

(d) Expected number of dwarf, white plants will be:

1/16 x 160 = 10.

Total number of tall F2 plants = 80 + 36 = 116

Total number of dwarf F2 plants = 39 + 5 = 44

Expected ratio of tall:dwarf plants according to Mendel = 3:1

Expected number of tall plants = 3/4 x 160 = 120

Expected number of dwarf plants = 1/4 x 160 = 40

Chi square $X^2$

= $\frac{(observed frequency - expected frequency)^2}{expected frequency}$

$X^2$ for tall = $\frac{(116 - 120)^2}{120}$

= 0.1333

$X^2$ for dwarf = $\frac{(44 - 40)^2}{40}$

= 0.40

Total $X^2$ = 0.1333 + 0.4

0.5333

Degree of freedom = n - 1

2 - 1 = 1

Tabulated $X^2$ (α = 0.05) = 3.841

Since the tabulated $X^2$ is more than the calculated $X^2$ , the hypothesis that the F2 data for stem length (tall:dwarf) is consistent with Mendel's law of segregation is accepted.

Observed Expected $X^2$

tall, violet flowers 80 90 $\frac{(80-90)^2}{90} = 1.11$

tall, white flowers 36 30 $\frac{(36-30)^2}{30} = 1.2$

dwarf, violet flowers 39 30 $\frac{(39-30)^2}{30} = 2.7$

dwarf, white flowers 5 10 $\frac{(5-10)^2}{10} = 2.5$

Total 160 160 7.51

Degree of freedom = 4 - 1 = 3

Tabulated $X^2$ (α = 0.05) = 7.815

The tabulated $X^2$ value is more than the calculated $X^2$ value. Hence, F2 data for stem length (tall:dwarf) and flower color (violet:white) is consistent with Mendel's law of independent assortment.
